Our construction follows from the corresponding $AdS_3/CFT_2$ scenario and involves a specific algebraic sum of the areas of bulk co dimension two static minimal surfaces homologous to appropriate subsystems. Utilizing our construction we compute the holographic entanglement negativity for such bipartite mixed state configurations of two disjoint subsystems with long rectangular strip geometries in $CFT_d$s dual to bulk pure $AdS_{d+1}$ geometries and the $AdS_{d+1}$-Schwarzschild black holes. \\ ( https://arxiv.org/abs/2001.10534 , 409kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10539 Date: Tue, 28 Jan 2020 19:00:00 GMT (36kb) Title: SW(3/2,2) subsymmetry in G$_2$, Spin(7) and N=2 CFTs Authors: Marc-Antoine Fiset Categories: hep-th math.QA Comments: 36 pages, 5 figures \\ Spectral flow, spacetime supersymmetry, topological twists, chiral primaries related to marginal deformations, mirror symmetry: these are important consequences of the worldsheet N=2 superconformal symmetry of strings on Calabi-Yau manifolds. To various degrees of certainty, these features were also established when the target is either 7d or 8d with exceptional holonomy G$_2$ or Spin(7) respectively. We show that these are more than mere analogies. We exhibit an underlying symmetry SW(3/2,2) making a bridge between the latter cases and K3 target spaces. Reviewing unitary representations of SW(3/2,2) leads us to speculate on further roles of this algebra in string theory compactifications and on the existence of topologically twisted versions of SW(3/2,2) theories. \\ ( https://arxiv.org/abs/2001.10539 , 36kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10542 Date: Tue, 28 Jan 2020 19:00:01 GMT (17kb,D) Title: Covariant formulation of BPS Black holes and the scalar weak gravity conjecture Authors: Gianguido Dall'Agata and Matteo Morittu Categories: hep-th Comments: 21 pages \\ In this note we analyze the BPS black hole equations in extended supergravities and we find two interesting relations involving first and second derivatives of combinations of the central charges. One relation is a new identity that solely relies on the geometric properties of the scalar manifolds of extended supergravity theories. The other relation is a generalization of a scalar weak gravity conjecture relation conjectured by Palti and uses properties of the underlying black hole solution. We also provide for the first time an explicit covariant construction of the BPS squared action for such solutions. \\ ( https://arxiv.org/abs/2001.10542 , 17kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10549 Date: Tue, 28 Jan 2020 19:00:03 GMT (800kb,D) Title: General Prescription for Global U(1)'s in 6D SCFTs Authors: Fabio Apruzzi, Marco Fazzi, Jonathan J. Heckman, Tom Rudelius, and Hao Y. Zhang Categories: hep-th Comments: 74 pages, 5 figures \\ We present a general prescription for determining the global U(1) symmetries of six-dimensional superconformal field theories (6D SCFTs). We use the quiver-like gauge theory description of the tensor branch to identify candidate U(1) symmetries which can act on generalized matter. The condition that these candidate U(1)'s are free of Adler-Bell-Jackiw (ABJ) anomalies provides bottom-up constraints for U(1)'s. This agrees with the answer obtained from symmetry breaking patterns induced by Higgs branch flows. We provide numerous examples illustrating the details of this proposal. In the F-theory realization of these theories, some of these symmetries originate from deformations of non-abelian flavor symmetries localized on a component of the discriminant, while others come from an additional generator of the Mordell-Weil group. We also provide evidence that some of these global U(1)'s do not arise from gauge symmetries, as would happen in taking a decoupling limit of a model coupled to six-dimensional supergravity. \\ ( https://arxiv.org/abs/2001.10549 , 800kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10553 Date: Tue, 28 Jan 2020 19:00:23 GMT (183kb,D) Title: The analytic structure of amplitudes on backgrounds from gauge invariance and the infra-red Authors: Anton Ilderton and Alexander J. MacLeod Categories: hep-th Comments: 25 pages, 4 figures \\ Gauge invariance and soft limits can be enough to determine the analytic structure of scattering amplitudes in certain theories. This prompts the question of how gauge invariance is connected to analytic structure in more general theories. Here we focus on QED in background plane waves. We show that imposing gauge invariance introduces new virtuality poles into internal momenta on which amplitudes factorise into a series of terms. Each term is gauge invariant, has a different analytic structure in external momenta, and exhibits a hard/soft factorisation. The introduced poles are dictated by infra-red behaviour, which allows us to extend our results to scalar Yukawa theory. The background is treated non-perturbatively throughout. \\ ( https://arxiv.org/abs/2001.10553 , 183kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10562 Date: Tue, 28 Jan 2020 19:14:10 GMT (353kb) Title: Correlation functions in massive Landau-Ginzburg orbifolds and tests of dualities Authors: Wei Gu Categories: hep-th Comments: 32 pages \\ In this paper we discuss correlation function computations in massive topological Landau-Ginzburg orbifolds, extending old results of Vafa.

Mishnyakov, A. Sleptsov, N. Tselousov Categories: hep-th math-ph math.GT math.MP math.QA \\ We present a new "tug-the-hook" symmetry of the colored Alexander polynomial which is the specialization of the quantum $\mathfrak{sl}_N$ invariant widely known as the colored HOMFLY-PT polynomial. In the perturbative expansion of the Alexander polynomial, this symmetry is realized as a property of the group theoretical data of the invariant. Mainly we study a general problem of finding elements in the center of the universal enveloping algebra satisfying the desired property. It is formulated in terms of polynomial relations on the Casimir invariants, which we solve explicitly providing a basis in the space of solutions to these relations. In that way we strongly restrict the general structures that could appear as the group theoretical part of the knot invariant. A combinatoric description of the problem and several ways of enumerating the solutions in terms of Young diagrams are given. Finally, we establish a connection of this newly observed symmetry with the eigenvalue conjecture, thus providing more evidence for both and taking a non-perturbative look at the symmetry. \\ ( https://arxiv.org/abs/2001.10596 , 21kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10744 Date: Wed, 29 Jan 2020 10:05:55 GMT (369kb,D) Title: Forces Between Kinks in $\phi^8$ Theory Authors: Peru d'Ornellas Categories: hep-th Comments: 21 pages, 13 figures \\ We investigate the dynamics of the kinks that emerge in a one-dimensional scalar field theory with an octic potential containing a quartic minimum and two quadratic minima. We show analytically that kink-antikink and kink-kink pairs interact with a force that scales with the fourth power of the inter-kink distance, and calculate its strength. This is done using two different techniques. The first employs a collective coordinate method to approximately solve the equation of motion for the profile of an accelerating kink. The second is based on modifying the potential to one that is able to support static solutions containing multiple kinks. We show that the two methods give consistent results. All calculations are supported by numerical work that confirms the validity of our results. \\ ( https://arxiv.org/abs/2001.10744 , 369kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10768 Date: Wed, 29 Jan 2020 11:57:51 GMT (8kb) Title: Holographic $\beta$ function in de Sitter space Authors: Hiroyuki Kitamoto, Yoshihisa Kitazawa Categories: hep-th gr-qc Comments: 5 pages Report-no: KEK-TH-2183, NCTS-TH-2002 \\ We investigate infrared logarithms in de Sitter space from holographic perspective. We employ a gravitational Fokker-Planck equation to investigate the time evolution of the de Sitter entropy $S=\pi/(G_N H^2)$, where $H$ is the Hubble parameter and $G_N$ is the Newton's constant. Under the Gaussian approximation, we obtain the dynamical $\beta$ function of $g=1/S$. It is asymptotically free toward the future. It also possesses the ultraviolet fixed point indicating that the Universe started the de Sitter expansion at the Planck scale.

Yan Categories: hep-th hep-ph Comments: 34 pages, 7 figures, 3 ancillary files Report-no: LAPTH-003/20, MPP-2020-8 \\ We present a method for calculating event shapes in QCD based on correlation functions of conserved currents. The method has been previously applied to the maximally supersymmetric Yang-Mills theory, but we demonstrate that supersymmetry is not essential. As a proof of concept, we consider the simplest example of a charge-charge correlation at one loop (leading order). We compute the correlation function of four electromagnetic currents and explain in detail the steps needed to extract the event shape from it. The result is compared to the standard amplitude calculation. The explicit four-point correlation function may also be of interest for the CFT community. \\ ( https://arxiv.org/abs/2001.10806 , 1004kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10864 Date: Wed, 29 Jan 2020 14:29:00 GMT (272kb,D) Title: On $\phi^3$ Theory Above Six Dimensions Authors: Junchen Rong, Jierong Zhu Categories: hep-th Comments: 13 pages, 4 figures \\ We study $\phi^3$ theory above six dimensions. The beta function $\beta(g)=-\epsilon g-\frac{3}{4}g^3$ in $d=6-2\epsilon$ dimensions has a UV fixed point when $\epsilon<0$. Like for $O(N)$ vector models above four dimensions, such a fixed point observed perturbatively in fact corresponds to a pair of complex CFTs separated by a branch cut. Using both numerical bootstrap and Gliozzi's fusion rule truncation method, we argue that such a CFT exist. \\ ( https://arxiv.org/abs/2001.10864 , 272kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10925 Date: Wed, 29 Jan 2020 16:13:11 GMT (8kb) Title: Analytical Solution for Gross-Pitaevskii Equation in Phase Space and Wigner Function Authors: A.

As a consequence a Non-Linear Schr\"odinger equation is derived in phase space. The formalism is based on the non-commutative structure of the star-product, and using the group theory approach as a guide a physically consistent theory is constructed in phase space. The state is described by a quasi-probability amplitude that is in association with the Wigner function. With these results, we solve the Gross-Pitaevskii equation in phase space and obtained the Wigner function for the system considered. \\ ( https://arxiv.org/abs/2001.10925 , 8kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10937 Date: Wed, 29 Jan 2020 16:23:46 GMT (811kb,D) Title: Renormalized Holographic Subregion Complexity under Relevant Perturbations Authors: Dongmin Jang, Yoonbai Kim, O-Kab Kwon, D.D. Tolla Categories: hep-th Comments: 30 pages, 1 figure \\ We construct renormalized holographic entanglement entropy (HEE) and subregion complexity (HSC) in the CV conjecture for asymptotically AdS$_4$ and AdS$_5$ geometries under relevant perturbations. Using the holographic renormalization method developed in the gauge/gravity duality, we obtain counter terms which are invariant under coordinate choices. We explicitly define different forms of renormalized HEE and HSC, according to conformal dimensions of relevant operators in the $d=3$ and $d=4$ dual field theories. We use a general embedding for arbitrary entangling subregions and showed that any choice of the coordinate system gives the same form of the counter terms, since they are written in terms of curvature invariants and scalar fields on the boundaries. We show an explicit example of our general procedure. Intriguingly, we find that a divergent term of the HSC in the asymptotically AdS$_5$ geometry under relevant perturbations with operators of conformal dimensions in the range $0< \Delta < \frac{1}{2}\,\, {\rm and} \,\, \frac{7}{2}< \Delta < 4$ cannot be cancelled out by adding any coordinate invariant counter term. This implies that the HSCs in these ranges of the conformal dimensions are not renormalizable covariantly. \\ ( https://arxiv.org/abs/2001.10937 , 811kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10947 Date: Wed, 29 Jan 2020 16:38:45 GMT (12kb) Title: Gauge generator for bi-gravity and multi-gravity models Authors: Ali Dokhani, Zahra Molaee, Ahmad Shirzad Categories: hep-th Comments: 12 pages \\ Following the Hamiltonian structure of bi-gravity and multi-gravity models in the full phase space, we have constructed the generating functional of diffeomorphism gauge symmetry.

When compactifying from 4d to 2d the dS solutions are metastable, whereas all higher dimensional cases are unstable. The existence of these dS solutions require that a certain inequality involving the derivatives of the potential and $p$-form gauge coupling is satisfied. This inequality is not satisfied in simple stringy examples (outside of the scope of Maldacena-Nu\~nez), which unsurprisingly avoid this route to dS solutions. We can apply our techniques to construct $dS_2$ solutions in the Standard Model plus an additional runaway scalar such as quintessence. Demanding that these are avoided leads to (weak) phenomenological constraints on the time variation of the fine structure constant and QCD axion-photon coupling. \\ ( https://arxiv.org/abs/2001.11023 , 248kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:2001.05469 (*cross-listing*) Date: Wed, 15 Jan 2020 18:33:57 GMT (1082kb,D) Date (revised v2): Tue, 28 Jan 2020 00:30:15 GMT (1084kb,D) Title: Cosmological constraints on dark energy in light of gravitational wave bounds Authors: Johannes Noller Categories: astro-ph.CO gr-qc hep-th Comments: 16 pages, 4 figures, 1 table; v2 minor clarifications added and typos corrected, results/equations/conclusions unchanged \\ Gravitational wave (GW) constraints have recently been used to significantly restrict models of dark energy and modified gravity. New bounds arising from GW decay and GW-induced dark energy instabilities are particularly powerful in this context, complementing bounds from the observed speed of GWs. We discuss the associated linear cosmology for Horndeski gravity models surviving these combined bounds and compute the corresponding cosmological parameter constraints, using CMB, redshift space distortion, matter power spectrum and BAO measurements from the Planck, SDSS/BOSS and 6dF surveys. The surviving theories are strongly constrained, tightening previous bounds on cosmological deviations from $\Lambda{}$CDM by over an order of magnitude. We also comment on general cosmological stability constraints and the nature of screening for the surviving theories, pointing out that a raised strong coupling scale can ensure compatibility with gravitational wave constraints, while maintaining a functional Vainshtein screening mechanism on solar system scales. Finally, we discuss the quasi-static limit as well as (constraints on) related observables for near-future surveys. \\ ( https://arxiv.org/abs/2001.05469 , 1084kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10606 (*cross-listing*) Date: Tue, 28 Jan 2020 22:01:25 GMT (57kb,D) Title: Cross-conductivity: novel transport coefficients to constrain the hadronic degrees of freedom of nuclear matter Authors: Jean-Bernard Rose, Moritz Greif, Jan Hammelmann, Jan A. Fotakis, Gabriel S. Denicol, Hannah Elfner and Carsten Greiner Categories: nucl-th hep-th Comments: 6 pages, 5 figures \\ In general, the constituents of the bulk matter produced in heavy-ion collisions carry, besides electric charge, multiple other conserved quantum numbers like baryon number and strangeness. Therefore, an electric field will not only generate an electric current but, at the same time, also currents in baryon number and strangeness. We propose that the impact of the electric field on these conserved currents should be characterized by additional transport coefficients, which we call cross-conductivities. In this paper, we introduce and present a calculation of these cross-conductivities from the Green-Kubo formalism within the transport code SMASH for different chemical compositions of hadron resonance gases. We find that the coefficients underlie an ordering in the active degrees of freedom and that thus the chemical composition of the system plays a crucial role. Further, we argue that in future comparisons of lattice QCD calculations with these findings, one could constrain which degrees of freedom and their corresponding charge properties are relevant for the QCD dynamics of the system. \\ ( https://arxiv.org/abs/2001.10606 , 57kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10701 (*cross-listing*) Date: Wed, 29 Jan 2020 06:18:43 GMT (395kb) Title: Neutron stars with a generalized Proca hair and spontaneous vectorization Authors: Ryotaro Kase, Masato Minamitsuji, and Shinji Tsujikawa Categories: gr-qc astro-ph.HE hep-ph hep-th Comments: 18 pages, 5 figures \\ In a class of generalized Proca theories, we study the existence of neutron star solutions with a nonvanishing temporal component of the vector field $A_\mu$ approaching 0 toward spatial infinity, as they may be the endpoints of tachyonic instabilities of neutron star solutions in general relativity with $A_{\mu}=0$. Such a phenomenon is called spontaneous vectorization, which is analogous to spontaneous scalarization in scalar-tensor theories with nonminimal couplings to the curvature or matter. For the nonminimal coupling $\beta X R$, where $\beta$ is a coupling constant and $X=-A_{\mu}A^{\mu}/2$, we show that there exist both 0-node and 1-node vector-field solutions, irrespective of the choice of the equations of state of nuclear matter. The 0-node solution, which is present only for $\beta=-{\cal O}(0.1)$, may be induced by some nonlinear effects such as the selected choice of initial conditions. The 1-node solution exists for $\beta=-{\cal O}(1)$, which suddenly emerges above a critical central density of star and approaches the general relativistic branch with the increasing central density. We compute the mass $M$ and radius $r_s$ of neutron stars for some realistic equations of state and show that the $M$-$r_s$ relations of 0-node and 1-node solutions exhibit notable difference from those of scalarized solutions in scalar-tensor theories. Finally, we discuss the possible endpoints of tachyonic instabilities. \\ ( https://arxiv.org/abs/2001.10701 , 395kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10796 (*cross-listing*) Date: Tue, 28 Jan 2020 06:30:09 GMT (8kb) Title: Saha Ionization and Particle production in Rainbow Rindler Metric Authors: Vishnu S Namboothiri Categories: gr-qc hep-th Comments: 8 pages \\ .The energy of a particle in the Rainbow Rindler metric is derived using Hamilton's variational principle. Saha Ionization equation and Pair production in Rainbow Rindler metric have been investigated. Saha ionization equation and Pair production in Rainbow Rindler metric depend on corrected acceleration which is energy-dependent, according to Rainbow Gravity theory. This means Energy(E) and metric tensor($g_{\mu \nu}(E)$) depends on the inertial observer. If the photo-ionization process and pair production observed in Rindler frame in rainbow gravity may assign particular energy(say $E$) and another observer may assign another energy ($E^{\prime}$) then corresponding metrics are also different. it is also possible that the same observer assigns energy to a particular process then he measures a different Energy to another process at the same place. In case of geometry also, not only different observers may see a given process or particle being affected by different metrics, but the same observer may assign different metrics to a different process or particle taking in the same region at the same time. This is required by covariance by the non-linear realization of the Lorentz group in momentum space. \\ ( https://arxiv.org/abs/2001.10796 , 8kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10826 (*cross-listing*) Date: Thu, 23 Jan 2020 12:31:40 GMT (24kb,D) Title: Singlets in the tensor product of an arbitrary number of Adjoint representations of SU(3) Authors: Prarit Agarwal, June Nahmgoong Categories: math.RT hep-ph hep-th math.GR Comments: 15 pages, 1 figure Report-no: QMUL-PH-20-02, KIAS-P20007 \\ We propose a set of 4 recurrence relations whose linear combination gives the number of group invariants, equivalently the dimension of the invariant subspace, in the tensor product of an arbitrary number of adjoint representations of the SU(3) Lie Group. \\ ( https://arxiv.org/abs/2001.10826 , 24kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10859 (*cross-listing*) Date: Wed, 29 Jan 2020 14:22:57 GMT (2707kb,D) Title: Prospects for large N gauge theories on the lattice Authors: Margarita Garcia Perez Categories: hep-lat hep-th Comments: 15 pages, 14 figures, Plenary talk given at the 37th International Symposium on Lattice Field Theory-Lattice 2019, 16-22 June 2019, Wuhan, China Report-no: IFT-UAM/CSIC-20-9 \\ I will review recent progress on addressing large N gauge theories on the lattice.

Therefore, an important scientific question to ask is whether the observed CMB map is consistent with Gaussian prediction. In this work we devise a new method where we use Rao's statistic based on sample arc-lengths to examine the validity of the hypothesis that the temperature field of the CMB is consistent with a Gaussian random field, by comprehensively testing correlations within a given $\ell$ mode and between nearby $\ell$ modes phases. This circular statistic is ordered and non-parametric. We performed our analysis on the scales limited by spherical harmonic modes $\le$ 128, to restrict ourselves to signal dominated region. To find the correlated sets of phases, we calculate the statistic for the data and 10000 Monte Carlo simulated random sets of phases and used 0.01 and 0.05 $\alpha$ levels to distinguish between statistically significant and highly significant detections. We apply our method on Planck satellite mission's final released CMB temperature anisotropy maps- COMMANDER, SMICA, NILC, and SEVEM along with WMAP 9 year released ILC map. We report that phases corresponding to some of the modes are non-uniform in these maps. We also report that most of the mode pairs are uncorrelated in each map, but a few are found to be correlated, which are different pairs in different maps. The detection of non-uniformity and correlations in the phases indicates presence of non Gaussian signals in the foreground minimized CMB maps. \\ ( https://arxiv.org/abs/2001.10960 , 472kb) ------------------------------------------------------------------------------ \\ arXiv:2001.10988 (*cross-listing*) Date: Wed, 29 Jan 2020 17:54:15 GMT (15kb) Title: Natural Philosophy versus Philosophy of Naturalness Authors: Goran Senjanovic Categories: hep-ph hep-ex hep-th physics.hist-ph Comments: Loosely based on the closing talk of the International conference 'LHC Days in Split 2018', September 2018, Split, Croatia \\ I reflect on some of the basic aspects of present day Beyond the Standard Model particle physics, focusing mostly on the issues of naturalness, in particular on the so-called hierarchy problem.

This topological state is analogous to the quantum Hall state. However, contrarily to the exact and extremely precise and robust quantization of the Hall conductance, the pumped charge is strictly quantized only when the pumping time is a multiple of a characteristic time scale, i.e., the pumping cycle duration. Here, we show instead that the pumped current becomes exactly quantized, independently from the pumping time, if the system is led into a quasiperiodic, incommensurate regime. In this quasiperiodic and topologically nontrivial state, the Bloch bands and the Berry curvature become flat, the pumped charge becomes linear in time, while the current becomes steady, topologically quantized, and proportional to the Chern number. The quantization of the current is exact up to exponentially small corrections. This has to be contrasted with the case of the commensurate (nonquasiperiodic) regime, where the current is not constant, and the pumped charge is quantized only at integer multiples of the pumping cycle. \\ ( https://arxiv.org/abs/2001.11022 , 1327kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1503.01757 (*cross-listing*) replaced with revised version Wed, 29 Jan 2020 07:54:02 GMT (96kb) Title: Landau-Ginzburg Mirror Symmetry Conjecture Authors: Weiqiang He, Si Li, Yefeng Shen and Rachel Webb Categories: math.AG hep-th Comments: 48 pages.
