We study geodesics, calculate Penrose limits and find the associated plane-wave geometries. We quantise the weakly coupled type-IIA string theory on these backgrounds. We study the BMN sector, finding operators that wrap the original quiver CFT. For the non-Abelian plane wave, we find a 'flow' in the frequencies. We report some progress to understand this, in terms of deconstruction of a higher dimensional field theory. We explore a relation with the plane-wave limit of the Janus solution, which we also provide. \\ ( https://arxiv.org/abs/1711.09911 , 52kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09913 Date: Mon, 27 Nov 2017 19:00:04 GMT (2610kb) Title: Renyi Entropy for Local Quenches in 2D CFTs from Numerical Conformal Blocks Authors: Yuya Kusuki, Tadashi Takayanagi Categories: hep-th cond-mat.stat-mech cond-mat.str-el quant-ph Comments: 22 pages, 8 figures Report-no: YITP-17-126, IPMU17-0163 \\ We study the time evolution of Renyi entanglement entropy for locally excited states in two dimensional large central charge CFTs. It generically shows a logarithmical growth and we compute the coefficient of $\log t$ term. Our analysis covers the entire parameter regions with respect to the replica number $n$ and the conformal dimension $h_O$ of the primary operator which creates the excitation. We numerically analyse relevant vacuum conformal blocks by using Zamolodchikov's recursion relation. We find that the behavior of the conformal blocks in two dimensional CFTs with a central charge $c$, drastically changes when the dimensions of external primary states reach the value $c/32$. In particular, when $h_O\geq c/32$ and $n\geq 2$, we find a new universal formula $\Delta S^{(n)}_A\simeq \frac{nc}{24(n-1)}\log t$. Our numerical results also confirm existing analytical results using the HHLL approximation. \\ ( https://arxiv.org/abs/1711.09913 , 2610kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09923 Date: Mon, 27 Nov 2017 19:00:20 GMT (51kb,D) Title: Gluons and gravitons at one loop from ambitwistor strings Authors: Yvonne Geyer, Ricardo Monteiro Categories: hep-th Comments: 36 pages, 5 figures \\ We present new and explicit formulae for the one-loop integrands of scattering amplitudes in non-supersymmetric gauge theory and gravity, valid for any number of particles. The results exhibit the colour-kinematics duality in gauge theory and the double-copy relation to gravity, in a form that was recently observed in supersymmetric theories. The new formulae are expressed in a particular representation of the loop integrand, with only one quadratic propagator, which arises naturally from the framework of the loop-level scattering equations. The starting point in our work are the expressions based on the scattering equations that were recently derived from ambitwistor string theory. We turn these expressions into explicit formulae depending only on the loop momentum, the external momenta and the external polarisations. These formulae are valid in any number of spacetime dimensions for pure Yang-Mills theory (gluon) and its natural double copy, NS-NS gravity (graviton, dilaton, B-field), and we also present formulae in four spacetime dimensions for pure gravity (graviton). We perform several tests of our results, such as checking gauge invariance and directly matching our four-particle formulae to previously known expressions. While these tests would be elaborate in a Feynman-type representation of the loop integrand, they become straightforward in the representation we use. \\ ( https://arxiv.org/abs/1711.09923 , 51kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09941 Date: Mon, 27 Nov 2017 19:27:16 GMT (47kb,D) Title: Ryu-Takayanagi Formula for Symmetric Random Tensor Networks Authors: Goffredo Chirco, Daniele Oriti, Mingyi Zhang Categories: hep-th gr-qc math-ph math.MP quant-ph Comments: 10 pages, 4 figures \\ We consider the special case of Random Tensor Networks (RTN) endowed with gauge symmetry constraints on each tensor. We compute the R\`enyi entropy for such states and recover the Ryu-Takayanagi (RT) formula in the large bond regime. The result provides first of all an interesting new extension of the existing derivations of the RT formula for RTNs. Moreover, this extension of the RTN formalism brings it in direct relation with (tensorial) group field theories (and spin networks), and thus provides new tools for realizing the tensor network/geometry duality in the context of background independent quantum gravity, and for importing quantum gravity tools in tensor network research. \\ ( https://arxiv.org/abs/1711.09941 , 47kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09949 Date: Mon, 27 Nov 2017 19:47:39 GMT (15kb) Title: A Non-Unitary Surprise Authors: Matthew Buican and Zoltan Laczko Categories: hep-th math.QA math.RT Comments: 7 pages; 1 appendix Report-no: QMUL-PH-17-28 \\ In various dimensions, we can sometimes compute observables of interacting conformal field theories (CFTs) that are connected to free theories via the renormalization group (RG) flow by computing protected quantities in the free theories. On the other hand, in two dimensions, it is often possible to algebraically construct observables of interacting CFTs using free fields without the need to explicitly construct an underlying RG flow. In this note, we begin to extend this idea to higher dimensions by showing that one can compute certain observables of an infinite set of unitary strongly interacting four-dimensional $\mathcal{N}=2$ superconformal field theories (SCFTs) by performing simple calculations involving sets of non-unitary free four-dimensional hypermultiplets. These free fields are distant cousins of the Majorana fermion underlying the two-dimensional Ising model and are not obviously connected to our interacting theories via an RG flow. Rather surprisingly, this construction gives us Lagrangians for particular observables in certain subsectors of many "non-Lagrangian" SCFTs by sacrificing unitarity while preserving the full $\mathcal{N}=2$ superconformal algebra. As a byproduct, we find relations between characters in unitary and non-unitary affine Kac-Moody algebras. We conclude by commenting on possible generalizations of our construction. \\ ( https://arxiv.org/abs/1711.09949 , 15kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09966 Date: Mon, 27 Nov 2017 20:17:19 GMT (253kb,D) Title: An Introduction to Pure Spinor Superstring Theory Authors: Nathan Berkovits and Humberto Gomez Categories: hep-th Comments: Villa de Leyva Summer School 2015 proceedings, 28 pages, 2 figures \\ In these lecture notes presented at the 2015 Villa de Leyva Summer School, we give an introduction to superstring theory.

We show that the two non-compact generators of the ISO(2) algebra correspond respectively to the residual gauge symmetry and its electromagnetic dual gauge symmetry that emerge at null infinity. The former is helicity universal (electric in nature) while the latter is helicity distinguishing (magnetic in nature). Thus, the conventional large gauge transformation is electric in nature, and is naturally associated with a scalar potential. We suggest that the electric Aharonov-Bohm effect is a direct measure for the electromagnetic memory arising from large gauge transformations. \\ ( https://arxiv.org/abs/1711.09968 , 65kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09993 Date: Mon, 27 Nov 2017 20:54:46 GMT (335kb,D) Title: Spinning strings and correlation functions in the AdS/CFT correspondence Authors: Juan Miguel Nieto Categories: hep-th Comments: 219 pages, 6 figures. PhD thesis based on the publications arXiv:1403.6651, arXiv:1407.7475, arXiv:1502.05203, arXiv:1707.08032 \\ In this thesis we present some computations made in both sides of the AdS/CFT holographic correspondence using the integrability of both theories. Regarding the string theory side, this thesis is focused in the computation of the dispersion relation of closed spinning strings in some deformed $AdS_3 \times S^3$ backgrounds. In particular we are going to focus in the deformation provided by the mixing of R-R and NS-NS fluxes and the so-called $\eta$-deformation. These computations are made using the classical integrability of these two deformed string theories, which is provided by the presence of a set of conserved quantities called "Uhlenbeck constants". The existence of the Uhlenbeck constants is central for the method used to derive the dispersion relations. Regarding the gauge theory side, we are interested in the computation of two and three-point correlation functions. Concerning the two-point function a computation of correlation functions involving different operators and different number of excitations is performed using the Algebraic Bethe Ansatz and the Quantum Inverse Scattering Method. These results are compared with computations done with the Coordinate Bethe Ansatz and with Zamolodchikov-Faddeev operators. Concerning the three-point functions, we will explore the novel construction given by the hexagon framework. In particular we are going to start from the already proposed hexagon form factor and rewrite it in a language more resembling of the Algebraic Bethe Ansatz. For this intent we construct an invariant vertex using Zamolodchikov-Faddeev operators, which is checked for some simple cases. \\ ( https://arxiv.org/abs/1711.09993 , 335kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10008 Date: Mon, 27 Nov 2017 21:31:47 GMT (2529kb,D) Title: Global Symmetries, Counterterms, and Duality in Chern-Simons Matter Theories with Orthogonal Gauge Groups Authors: Clay Cordova, Po-Shen Hsin, Nathan Seiberg Categories: hep-th cond-mat.str-el Comments: 71 pages, 7 figures, 5 tables \\ We study three-dimensional gauge theories based on orthogonal groups. Depending on the global form of the group these theories admit discrete $\theta$-parameters, which control the weights in the sum over topologically distinct gauge bundles. We derive level-rank duality for these topological field theories. Our results may also be viewed as level-rank duality for $SO(N)_{K}$ Chern-Simons theory in the presence of background fields for discrete global symmetries. In particular, we include the required counterterms and analysis of the anomalies. We couple our theories to charged matter and determine how these counterterms are shifted by integrating out massive fermions. By gauging discrete global symmetries we derive new boson-fermion dualities for vector matter, and present the phase diagram of theories with two-index tensor fermions, thus extending previous results for $SO(N)$ to other global forms of the gauge group. \\ ( https://arxiv.org/abs/1711.10008 , 2529kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10026 Date: Mon, 27 Nov 2017 22:34:45 GMT (16kb) Title: Ultraviolet Properties of the Self-Dual Yang-Mills Theory Authors: Andrey Losev, Igor Polyubin, and Alexei Rosly Categories: hep-th Comments: 15 pages \\ We compute the ultraviolet divergences in the self-dual Yang-Mills theory, both in the purely perturbative (zero instanton charge) and topologically non-trivial sectors.

The fundamental degrees of freedom are $2N$ bosonic fields living on the future conformal boundary, where $N$ is proportional to the de Sitter horizon entropy. The vacuum state is normalizable. The model agrees in perturbation theory with expectations from a previously proposed dS-CFT description in terms of a fermionic Sp(N) model, but it goes beyond this, both in its conceptual scope and in its computational power. In particular it resolves the apparent pathologies affecting the Sp(N) model, and it provides an exact formula for late time vacuum correlation functions. We illustrate this by computing probabilities for arbitrarily large field excursions, and by giving fully explicit examples of vacuum 3- and 4-point functions. We discuss bulk reconstruction and show the perturbative bulk QFT canonical commutations relations can be reproduced from the fundamental operator algebra, but only up to a minimal error term $\sim e^{-\mathcal{O}(N)}$, and only if the operators are coarse grained in such a way that the number of accessible "pixels" is less than $\mathcal{O}(N)$. Independent of this, we show that upon gauging the higher spin symmetry group, one is left with $2N$ physical degrees of freedom, and that all gauge invariant quantities can be computed by a $2N \times 2N$ matrix model. This suggests a concrete realization of the idea of cosmological complementarity. \\ ( https://arxiv.org/abs/1711.10037 , 3941kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10053 Date: Tue, 28 Nov 2017 00:01:53 GMT (23kb) Title: Quantum deformation of planar amplitudes Authors: Michael Movshev, Albert Schwarz Categories: hep-th math-ph math.MP math.QA \\ In maximally supersymmetric four-dimensional gauge theories planar on-shell diagrams are closely related to the positive Grassmannian and the cell decomposition of it into the union of so called positroid cells \cite{A}. We establish that volume forms on positroids used to express scattering amplitudes can be $q$-deformed to Hochschild homology classes of corresponding quantum algebras. The planar amplitudes are represented in \cite {A} as sums of contributions of some set of positroid cells; we quantize these contributions. In classical limit our considerations allow us to obtain explicit formulas for contributions of positroid cells to scattering amplitudes. \\ ( https://arxiv.org/abs/1711.10053 , 23kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10142 Date: Tue, 28 Nov 2017 06:35:31 GMT (17kb) Title: Gauge copies in the Landau-DeWitt gauge: a background invariant restriction Authors: D. Dudal and D. Vercauteren Categories: hep-th hep-lat hep-ph Comments: 14 pages \\ The Landau background gauge, also known as the Landau-DeWitt gauge, has found renewed interest during the past decade given its usefulness in accessing the confinement-deconfinement transition via the vacuum expectation value of the Polyakov loop, describable via an appropriate background. In this Letter, we revisit this gauge from the viewpoint of it displaying gauge (Gribov) copies. We generalize the Gribov-Zwanziger effective action in a BRST and background invariant way; this action leads to a restriction on the allowed gauge fluctuations, thereby eliminating the infinitesimal background gauge copies. The explicit background invariance of our action is in contrast with earlier attempts to write down and use an effective Gribov-Zwanziger action. It allows to address certain subtleties arising in these earlier works, such as a spontaneous and thus spurious Lorentz symmetry breaking, something which is now averted. \\ ( https://arxiv.org/abs/1711.10142 , 17kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10195 Date: Tue, 28 Nov 2017 09:24:17 GMT (317kb,D) Title: B-branes and supersymmetric quivers in 2d Authors: Cyril Closset, Jirui Guo and Eric Sharpe Categories: hep-th Comments: 63 pages plus appendix, 21 figures Report-no: CERN-TH-2017-244 \\ We study 2d $\mathcal{N}=(0,2)$ supersymmetric quiver gauge theories that describe the low-energy dynamics of D1-branes at Calabi-Yau fourfold (CY$_4$) singularities. On general grounds, the holomorphic sector of these theories---matter content and (classical) superpotential interactions---should be fully captured by the topological $B$-model on the CY$_4$. By studying a number of examples, we confirm this expectation and flesh out the dictionary between B-brane category and supersymmetric quiver: the matter content of the supersymmetric quiver is encoded in morphisms between B-branes (that is, Ext groups of coherent sheaves), while the superpotential interactions are encoded in the $A_\infty$ algebra satisfied by the morphisms. This provides us with a derivation of the supersymmetric quiver directly from the CY$_4$ geometry. We also suggest a relation between triality of $\mathcal{N}=(0,2)$ gauge theories and certain mutations of exceptional collections of sheaves. 0d $\mathcal{N}=1$ supersymmetric quivers, corresponding to D-instantons probing CY$_5$ singularities, can be discussed similarly. \\ ( https://arxiv.org/abs/1711.10195 , 317kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10252 Date: Tue, 28 Nov 2017 12:32:20 GMT (11kb) Title: Massive mixed symmetry field dynamics in open bosonic string theory Authors: V.A.

Tatsuishi Categories: hep-th hep-ph Comments: 19 pages, 4 figures Report-no: EPHOU-17-015, WU-HEP-17-015 \\ We propose a new type of K\"ahler moduli stabilization in type IIB superstring theory on Calabi-Yau manifolds with positive Euler number. By an existence of radiative corrections due to sparticles, overall K\"ahler modulus can be perturbatively stabilized at the supersymmetry-breaking anti-de Sitter minimum without tuning the flux-induced superpotential. The structure of moduli stabilization is maintained even if the anti-de Sitter minimum is uplifted to de Sitter vacuum by the introduction of anti-D branes. Although the existence of vacuum depends on the value of cutoff scale and degeneracies of sparticles, there exist the parameter spaces where Kaluza-Klein and stringy modes are heavier than the cutoff scale. Furthermore, this stabilization scenario predicts an ultralight axion. \\ ( https://arxiv.org/abs/1711.10274 , 78kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10287 Date: Tue, 28 Nov 2017 13:38:17 GMT (38kb) Title: Probing Fuzzballs with Particles, Waves and Strings Authors: M.

To this end, we study geodetic motion, Klein-Gordon equation and string scattering in the resulting gravitational background. Due to the reduced rotational symmetry, even in the simple case of a circular fuzzball, the system generically cannot be integrated. Yet, for motion in the plane of the string profile or in the orthogonal plane to it, one can compute the deflection angle or the phase shift and identify the critical impact parameter, below which even a massless probe is captured by the fuzzball if its internal momentum is properly tuned. We find agreement among the three approaches, thus giving further support to the fuzzball proposal at the dynamical level. \\ ( https://arxiv.org/abs/1711.10287 , 38kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10308 Date: Tue, 28 Nov 2017 14:29:07 GMT (6kb) Title: Superfield generating equation of field-antifield formalism Authors: I.

It is widely believed that massive gravity models with six degrees of freedom have an unavoidable ghost-like instability; however, the corresponding medium has stable phonon-like excitations. The apparent contradiction is solved by the presence of a non-vanishing background pressure and energy density of the medium that opens up a stability window. The result is confirmed by looking at linear stability on an expanding Universe, recovering the flat space stability conditions in the small wavelength limit. Moreover, one can show that under rather mild conditions, no ghost-like instability is present for any wavelength. As a result, exploiting the medium interpretation, a generic massive gravity model with six degrees of freedom is perfectly viable. \\ ( https://arxiv.org/abs/1711.10424 , 21kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10472 Date: Tue, 28 Nov 2017 18:59:29 GMT (505kb,D) Title: Massive gravity and the suppression of anisotropies and gravitational waves in a matter-dominated contracting universe Authors: Chunshan Lin, Jerome Quintin, Robert H.

References added Report-no: PI/UAN-2017-615FT \\ We study the role that a cosmic triad in the generalized $SU(2)$ Proca theory, specifically in one of the pieces of the Lagrangian that involves the symmetric version $S_{\mu \nu}$ of the gauge field strength tensor $F_{\mu \nu}$, has on dark energy and primordial inflation. Regarding dark energy, the triad behaves asymptotically as a couple of radiation perfect fluids whose energy densities are negative for the $S$ term but positive for the Yang-Mills term. This leads to an interesting dynamical fine-tuning mechanism that gives rise to a combined equation of state parameter $\omega \simeq -1$ and, therefore, to an eternal period of accelerated isotropic expansion for an ample spectrum of initial conditions. Regarding primordial inflation, one of the critical points of the associated dynamical system can describe a prolonged period of isotropic slow-roll inflation sustained by the $S$ term. This period ends up when the Yang-Mills term dominates the energy density leading to the radiation dominated epoch. Unfortunately, in contrast to the dark energy case, the primordial inflation scenario is strongly sensitive to the coupling constants and initial conditions. The whole model, including the other pieces of the Lagrangian that involve $S_{\mu \nu}$, might evade the recent strong constraints coming from the gravitational wave signal GW170817 and its electromagnetic counterpart GRB 170817A. \\ ( https://arxiv.org/abs/1711.01935 , 269kb) ------------------------------------------------------------------------------ \\ arXiv:1711.04534 (*cross-listing*) Date: Mon, 13 Nov 2017 11:42:02 GMT (13kb) Title: The Cosmological Fate of $SU(3)_C \times U(1)_{EM}$ Authors: Jennifer Rittenhouse West Categories: hep-ph hep-th Comments: 4 pages Report-no: UCI-HEP-TR-2017-15 \\ Under the assumption that the current epoch of the Universe is not special, i.e. is not the final state of a long history of processes in particle physics, the breaking of $SU(3)_C \times U(1)_{EM}$ is investigated. Spontaneous symmetry breaking of $U(1)_{EM}$ is carried out and the electromagnetically charged scalar field $\phi$ is found to be ruled out for all experimentally viable masses. In this case, electromagnetism will continue to be a long range force for the lifetime of the Universe. $SU(3)_C$ is tested for complementarity, in which the confinement phase of QCD $+$ colored scalars is equivalent to a spontaneously broken $SU(3)$ gauge theory. If complementarity is not applicable, $SU(3)_C$ has multiple symmetry breaking paths with various final symmetry structures.

In particular, we vary the parameters in the Hamiltonian as a function of time, and investigate the temporal behavior of the system from the Mott insulator to the superfluid (SF) crossing a second-order phase transition. We first solve a time-dependent Schr\"odinger equation for the experimental setup recently done by Braun et.al. [Proc. Nat. Acad. Sci. 112, 3641 (2015)] and show that the numerical and experimental results are in fairly good agreement. However, these results disagree with the Kibble-Zurek scaling. From our numerical study, we reveal a possible source of the discrepancy. Next, we calculate the critical exponents of the correlation length and vortex density in addition to the SF order parameter for a Kibble-Zurek protocol. We show that beside the "freeze" time $\hat{t}$, there exists another important time, $t_{\rm eq}$, at which an oscillating behavior of the SF amplitude starts. From calculations of the exponents of the correlation length and vortex density with respect to a quench time $\tQ$, we obtain a physical picture of a coarsening process. Finally, we study how the system evolves after the quench. We give a global picture of dynamics of the Bose-Hubbard model. \\ ( https://arxiv.org/abs/1711.08882 , 4376kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09891 (*cross-listing*) Date: Mon, 27 Nov 2017 10:33:38 GMT (74kb,D) Title: Scalar-metric quantum cosmology with Chaplygin gas and perfect fluid Authors: Saumya Ghosh, Sunandan Gangopadhyay, Prasanta K. Panigrahi Categories: gr-qc hep-th Comments: 8 pages LateX \\ In this paper we consider the flat FRW cosmology with a scalar field coupled with the metric along with generalized Chaplygin gas and perfect fluid comprising the matter sector. We use the Schutz's formalism to deal with the generalized Chaplygin gas sector. The full theory is then quantized canonically using the Wheeler-DeWitt Hamiltonian formalism. We then solve the WD equation with appropriate boundary conditions. Then by defining a proper completeness relation for the self-adjointness of the WD equation we arrive at the wave packet for the universe. It is observed that the peak in the probability density gets affected due to both fluids in the matter sector, namely, the Chaplygin gas and perfect fluid. \\ ( https://arxiv.org/abs/1711.09891 , 74kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09893 (*cross-listing*) Date: Mon, 27 Nov 2017 15:21:23 GMT (66kb) Title: A general theory of linear cosmological perturbations: stability conditions, the quasistatic limit and dynamics Authors: Macarena Lagos, Emilio Bellini, Johannes Noller, Pedro G. Ferreira, Tessa Baker Categories: gr-qc hep-th \\ We analyse cosmological perturbations around a homogeneous and isotropic background for scalar-tensor, vector-tensor and bimetric theories of gravity. Building on previous results, we propose a unified view of the effective parameters of all these theories. Based on this structure, we explore the viable space of parameters for each family of models by imposing the absence of ghosts and gradient instabilities. We then focus on the quasistatic regime and confirm that all these theories can be approximated by the phenomenological two-parameter model described by an effective Newton's constant and the gravitational slip. Within the quasistatic regime we pinpoint signatures which can distinguish between the broad classes of models (scalar-tensor, vector-tensor or bimetric). Finally, we present the equations of motion for our unified approach in such a way that they can be implemented in Einstein-Boltzmann solvers. \\ ( https://arxiv.org/abs/1711.09893 , 66kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09915 (*cross-listing*) Date: Mon, 27 Nov 2017 19:00:06 GMT (126kb,D) Title: Primordial black holes from fifth forces Authors: Luca Amendola, Javier Rubio, Christof Wetterich Categories: astro-ph.CO gr-qc hep-th Comments: 5 pages, 1 figure \\ Primordial black holes can be produced by a long range attractive fifth force stronger than gravity, mediated by a light scalar field interacting with non-relativistic "heavy" particles. As soon as the energy fraction of heavy particles reaches a threshold, the fluctuations rapidly grow non-linear. The overdensities collapse into black holes or similar screened objects, without the need of any particular feature in the spectrum of primordial density fluctuations generated during inflation. We discuss if such primordial black holes can constitute the total dark matter component in the Universe. \\ ( https://arxiv.org/abs/1711.09915 , 126kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09925 (*cross-listing*) Date: Mon, 27 Nov 2017 19:01:15 GMT (1647kb,D) Title: Topological order in the pseudogap metal Authors: Mathias S. Scheurer, Shubhayu Chatterjee, Wei Wu, Michel Ferrero, Antoine Georges, Subir Sachdev Categories: cond-mat.str-el hep-th Comments: 8+15 pages, 10 figures \\ We compute the electronic Green's function of the topologically ordered Higgs phase of a SU(2) gauge theory of fluctuating antiferromagnetism on the square lattice. The results are compared with cluster extensions of dynamical mean field theory, and quantum Monte Carlo calculations, on the pseudogap phase of the strongly interacting hole-doped Hubbard model. Good agreement is found in the momentum, frequency, hopping, and doping dependencies of the spectral function and electronic self-energy. We show that lines of (approximate) zeros of the zero-frequency electronic Green's function are signs of the underlying topological order of the gauge theory, and describe how these lines of zeros appear in our theory of the Hubbard model. We also derive a modified, non-perturbative version of the Luttinger theorem that holds in the Higgs phase. \\ ( https://arxiv.org/abs/1711.09925 , 1647kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09930 (*cross-listing*) Date: Mon, 27 Nov 2017 19:04:54 GMT (18kb) Title: Teleparallel theories of gravity as analogue of non-linear electrodynamics Authors: Manuel Hohmann, Laur J\"arv, Martin Kr\v{s}\v{s}\'ak, Christian Pfeifer Categories: gr-qc hep-th math-ph math.MP Comments: 12 pages, no figures \\ The teleparallel formulation of gravity theories reveals close structural analogies to electrodynamics, which are more hidden in their usual formulation in terms of the curvature of spacetime. We show how every locally Lorentz invariant teleparallel theory of gravity with second order field equations can be understood as built from a gravitational field strength and excitation tensor which are related to each other by a constitutive relation, analogous to the axiomatic construction of theories of electrodynamics. We demonstrate how the previously studied models of $f(\mathbb{T})$ and $f(T_\text{ax},T_\text{ten},T_\text{vec})$ gravity as well as teleparallel dark energy can be formulated in this language. The advantage of this approach to gravity is that the field equations for different models all take the same compact form and general results can be obtained. An important new such result we find is a constraint which relates the field equations of the tetrad and the spin connection. \\ ( https://arxiv.org/abs/1711.09930 , 18kb) ------------------------------------------------------------------------------ \\ arXiv:1711.09950 (*cross-listing*) Date: Mon, 27 Nov 2017 19:48:05 GMT (11kb) Title: The number of independent Traces and Supertraces on the Symplectic Reflection Algebra $H_{1,\nu}(\Gamma \wr S_N)$ Authors: S.E.

This is not forbidden by topological censorship, since all the known energy inequalities needed to prove the spherical topology of $\Sigma$ are violated in quantum theory. We choose the systoles of $\Sigma$ to encode its complexity, which gives rise to the black hole entropy. We present hand-waving reasons why the entropy of the black hole can be considered as a function of the volume entropy of $\Sigma$. We focus on the limiting case of $\Sigma$ having a large genus. \\ ( https://arxiv.org/abs/1711.09963 , 17kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10029 (*cross-listing*) Date: Mon, 27 Nov 2017 22:45:03 GMT (5872kb) Title: The Top Quark: Past, Present, and Future Authors: R.

Categories: gr-qc hep-ph hep-th Comments: v1: 8 pages, 5 figures \\ In cosmological framework, Noether symmetry technique has revealed a useful tool in order to examine exact solutions. In this work, we analyse the dynamics of the field in the cosmological alpha-attractors using the Noether sysmetry technique by focusing on the single field scenario in the Einstein-frame form. We show that with a Noether symmetry the coresponding dynamical system can be completely integrated and the potential exhibited by the symmetry can be exactly obtained. Interestingly, the solutions of the system can possibly describe the transition from a decelerated to an accelerated expansion of the universe dictated from the scale factor. With the proper choice of parameters, the behavior of the scale factor shows the time-dependence with positively rational exponents at very early stage. Surprisingly, for all cases it has an exponential (de Sitter) behavior at the present epoch. Moreover, we discover that the Hubble parameters strongly depends on the initial values of parameters exhibited by the Noether symmetry. It is also constant in the present epoch in all cases. However, by properly choosing the initial values of the parameters, it can retardedly evolve before its values become a constant at the present epoch. \\ ( https://arxiv.org/abs/1711.10080 , 87kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10086 (*cross-listing*) Date: Tue, 28 Nov 2017 02:16:10 GMT (559kb) Title: 3D structure of hadrons by generalized distribution amplitudes and gravitational form factors Authors: S.

The GDA studies provide information on three-dimensional tomography of hadrons. The GDAs can be investigated by the two-photon process $\gamma^* \gamma \to h\bar h$, and the GPDs are studied by the deeply virtual Compton scattering $\gamma^* h \to \gamma h$. The GDA studies had been pure theoretical topics, although the GPDs have been experimentally investigated, because there was no available experimental measurement. Recently, the Belle collaboration reported their measurements on the $\gamma^* \gamma \to \pi^0 \pi^0$ differential cross section, so that it became possible to find the GDAs from their measurements. Here, we report our analysis of the Belle data for determining the pion GDAs. From the GDAs, the timelike gravitational form factors $\Theta_1 (s)$ and $\Theta_2 (s)$ can be calculated, which are mechanical (pressure, shear force) and mass (energy) form factors, respectively. They are converted to the spacelike form factors by using the dispersion relation, and then gravitational radii are evaluated for the pion. The mass and mechanical radii are obtained from $\Theta_2$ and $\Theta_1$ as $\sqrt {\langle r^2 \rangle_{\text{mass}}} =0.56 \sim 0.69$ fm and $\sqrt {\langle r^2 \rangle_{\text{mech}}} =1.45 \sim 1.56$ fm, whereas the experimental charge radius is $\sqrt {\langle r^2 \rangle_{\text{charge}}} =0.672 \pm 0.008$ fm for the charged pion.

We establish a connection between singularities in the Borel plane and quark-hadron duality violating contributions. Starting with the assumption that for QCD at $N_c=\infty$ the spectrum approaches a Regge trajectory at large energy, we obtain an expression for quark-hadron duality violations at large, but finite $N_c$. \\ ( https://arxiv.org/abs/1711.10316 , 221kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10333 (*cross-listing*) Date: Tue, 28 Nov 2017 15:14:26 GMT (26kb) Title: Canonical transformation path to gauge theories of gravity II --- Spacetime coupling of massive spin particle fields Authors: J. Struckmeier, P. Liebrich, J. Muench, M. Hanauske, J. Kirsch, D. Vasak, L. Satarov, H. Stoecker Categories: gr-qc hep-th nucl-th Comments: 12 pages \\ The generic form of spacetime dynamics as a gauge theory has recently been derived, based on only the action principle and on the general principle of relativity. In the present paper, the physical consequences are discussed. The gauge coupling terms obtained imply that Einstein's theory holds only for structureless (spin zero) particles, and aggregations of them. For massive particles with spin, however, spacetime dynamics is to be described by an additional, Poisson-type equation describing the interaction of the particle's spin with the torsion of spacetime. This equation shows that torsion propagates with gravitational waves. Spin carrying matter is thus shown to couple with the torsion of spacetime. The proper source term for the spacetime dynamics is given by the canonical energy-momentum tensor---which embraces also the energy density furnished by microscopic internal spin. This changes the model of compact astrophysical objects and of relativistic collapse dynamics, with significant impact on the description of binary neutron star mergers and pulsar dynamics. The final generally covariant Hamiltonian must contain a term quadratic in the conjugate momenta of the gauge fields in order to yield a closed system of field equations---in analogy to all other Hamiltonian descriptions of field theories. The fact that the canonical gauge theory of gravity derived here requires that both, quadratic curvature tensors and canonical energy momentum tensors, enter the field equation for the spacetime dynamics leads to a qualitatively new framework for general relativity---and to a new understanding of Friedman cosmology and the cosmological constant problem. \\ ( https://arxiv.org/abs/1711.10333 , 26kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10390 (*cross-listing*) Date: Tue, 28 Nov 2017 16:45:59 GMT (6kb) Title: Symmetries of the dynamics and Noether theorem in classical mechanics Authors: Franco Strocchi Categories: physics.class-ph hep-th Comments: 7 pages MSC-class: 70 Hxx, 70 Gxx \\ The aim of this note is to discuss the relation between one-parameter continuous symmetries of the dynamics, defined on physical grounds, and conservation laws.

In this more general case, the corresponding formulation of Noether theorem gives that the conservation law displays a sort of ano\-ma\-ly, the constant of motion being the sum of the canonical generator of the symmetry transformations plus the generator $G$ of the gauge transformation $q_i \rightarrow q_i$, $p_i \rightarrow p_i - \partial G/ \partial q_i$. \\ ( https://arxiv.org/abs/1711.10390 , 6kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10391 (*cross-listing*) Date: Tue, 28 Nov 2017 16:46:04 GMT (67kb,D) Title: Effective description of general extensions of the Standard Model: the complete tree-level dictionary Authors: J. de Blas, J.

If they are primordial black holes (PBH), the merger rates inferred by LIGO coincide with the ones expected for abundances comparable to those of Dark Matter (DM). By re-investigating some observations, such as microlensing and compact star clusters in faint dwarf galaxies, and by analyzing the latest LIGO data, we identify seven hints pointing towards PBH-DM, with a broad mass spectrum centered in the range $[1-10] M_\odot$. The detection of numerous micro-lensing events of distant quasars and stars in M31 provide firm evidences that 15%-25% of the halo of massive galaxies is made of compact objects with masses $[0.05-0.45] M_\odot$ and $[0.5-1] M_\odot$ respectively, such as a primordial black holes. These values are compatible with the re-constructed PBH mass spectrum from LIGO events. Altogether, for a log-normal distribution, we find best fit values for the central mass $\mu \approx 3 M_\odot$ and a width $ \sigma \approx 0.5 $. On the other hand, this scenario passes all the other current constraints on PBH abundances. Moreover, we show by using first physical principles that it would naturally explain the missing dwarf satellites, too-big-to-fail, core/cusp and missing baryon problems as well as the observation of super-massive black holes at high redshifts that would have grown from primordial seeds in the tail of the PBH mass distribution. In this scenario, between 0.1% and 1% of the events detected by LIGO will involve a PBH with a mass below the Chandrasekhar mass, which would unambiguously prove the existence of PBH. \\ ( https://arxiv.org/abs/1711.10458 , 857kb) ------------------------------------------------------------------------------ \\ arXiv:1711.10473 (*cross-listing*) Date: Tue, 28 Nov 2017 18:59:59 GMT (129kb,D) Title: Chiral tricritical point: a new universality class in Dirac systems Authors: Shuai Yin, Shao-Kai Jian, Hong Yao Categories: cond-mat.str-el cond-mat.mes-hall hep-th Comments: 4.5 pages + supplemental material, 2 figures \\ We explore the universal properties of a chiral tricritical point (CTP) in two-dimensional Dirac semimetals which is a new universality class obtained by coupling massless Dirac fermions to the tricritical point. We construct a microscopic model of Dirac fermions coupled to Ising variables on the honeycomb lattice and find a (first- or second-order depending on model parameters) quantum phase transition between a Dirac semimetal and a charge-density-wave insulator as a function of transverse fields. The CTP appears at the point where the first- and second-order phase transition meet while its universal properties remain unknown. From functional renormalization group analysis of the effective action, we obtain the critical behaviors of the CTP, which are qualitatively distinct from both the tricritical Ising universality and the chiral Ising universality. We future extend the calculations of the chiral tricritical behaviors to the case of Heisenberg variables. The experimental relevance of the CTP in two-dimensional Dirac semimetals is also discussed. \\ ( https://arxiv.org/abs/1711.10473 , 129kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1608.05363 replaced with revised version Tue, 28 Nov 2017 15:38:01 GMT (199kb,D) Title: (2,2) and (0,4) Supersymmetric Boundary Conditions in 3d N = 4 Theories and Type IIB Branes Authors: Hee-Joong Chung, Tadashi Okazaki Categories: hep-th Comments: 46 pages, 4 figures; v3: published version in Physical Review D Report-no: KIAS-P16058, NCTS-TH/1605 Journal-ref: Phys.
