We find dualities for the superconformal field theories similar to the 4d ${\cal N}=2$ theories of class ${\cal S}$, labelled by a Riemann surface ${\cal C}$. The dual descriptions arise from various pair-of-pants decompositions, that involves an analog of the $T_N$ theory. Especially, we find the superconformal index of such theories can be written in terms of a topological field theory on ${\cal C}$. We interpret this class of SCFTs as the ones coming from compactifying 6d ${\cal N}=(2, 0)$ theory on $\mathbb{CP}^1 \times {\cal C}$ \\ ( http://arxiv.org/abs/1505.07110 , 121kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07116 Date: Tue, 26 May 2015 20:00:54 GMT (115kb,D) Title: Quantum Cohomology and Quantum Hydrodynamics from Supersymmetric Quiver Gauge Theories Authors: Giulio Bonelli, Antonio Sciarappa, Alessandro Tanzini and Petr Vasko Categories: hep-th math-ph math.MP nlin.SI Comments: 70 pages, 2 figures. Invited contribution to Journal of Geometry and Physics, special issue "Instanton Counting: Moduli Spaces, Representation Theory and Integrable Systems" \\ We study the connection between N = 2 supersymmetric gauge theories, quantum cohomology and quantum integrable systems of hydrodynamic type. We consider gauge theories on ALE spaces of A and D-type and discuss how they describe the quantum cohomology of the corresponding Nakajima's quiver varieties. We also discuss how the exact evaluation of local BPS observables in the gauge theory can be used to calculate the spectrum of quantum Hamiltonians of spin Calogero integrable systems and spin Intermediate Long Wave hydrodynamics. This is explicitly obtained by a Bethe Ansatz Equation provided by the quiver gauge theory in terms of its adjacency matrix. \\ ( http://arxiv.org/abs/1505.07116 , 115kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07120 Date: Tue, 26 May 2015 20:04:38 GMT (474kb) Title: Large N non-perturbative effects in $\mathcal{N}=4$ superconformal Chern-Simons theories Authors: Yasuyuki Hatsuda, Masazumi Honda and Kazumi Okuyama Categories: hep-th Comments: 35+18 pages, 3 figures Report-no: DESY 15-078, HRI/ST/1505 \\ We investigate the large $N$ instanton effects of partition functions in a class of $\mathcal{N}=4$ circular quiver Chern-Simons theories on a three-sphere. Our analysis is based on the supersymmetry localization and the Fermi-gas formalism. The resulting matrix model can be regarded as a two-parameter deformation of the ABJM matrix model, and has richer non-perturbative structures. Based on a systematic semi-classical analysis, we find analytic expressions of membrane instanton corrections. We also exactly compute the partition function for various cases and find some exact forms of worldsheet instanton corrections, which appear as quantum mechanical non-perturbative corrections in the Fermi-gas system. \\ ( http://arxiv.org/abs/1505.07120 , 474kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07131 Date: Tue, 26 May 2015 20:39:17 GMT (1685kb) Title: Quantum state of the black hole interior Authors: Ram Brustein, A.J.M. Medved Categories: hep-th gr-qc Comments: 28 pages, 2 figures \\ If a black hole (BH) is initially in an approximately pure state and it evaporates by a unitary process, then the emitted radiation will be in a highly quantum state. As the purifier of this radiation, the state of the BH interior must also be in some highly quantum state. So that, within the interior region, the mean-field approximation cannot be valid and the state of the BH cannot be described by some semiclassical metric. On this basis, we model the state of the BH interior as a collection of a large number of excitations that are packed into closely spaced but single-occupancy energy levels; a sort-of "Fermi sea" of all light-enough particles. This highly quantum state is surrounded by a semiclassical region that lies close to the horizon and has a non-vanishing energy density. It is shown that such a state looks like a BH from the outside and decays via gravitational pair production in the near-horizon region at a rate that agrees with the Hawking rate. We also consider the fate of a classical object that has passed through to the BH interior and show that, once it has crossed over the near-horizon threshold, the object meets its demise extremely fast. This result cannot be attributed to a "firewall", as the trauma to the in-falling object only begins after it has passed through the near-horizon region and enters a region where semiclassical spacetime ends but the energy density is still parametrically smaller than Planckian. \\ ( http://arxiv.org/abs/1505.07131 , 1685kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07270 Date: Wed, 27 May 2015 11:42:52 GMT (2030kb,D) Title: On the influence of Gribov ambiguities in a class of nonlinear covariant gauges Authors: Julien Serreau (1) and Mattheiu Tissier (2) and Andr\'eas Tresmontant (1 and 2) ((1) Astro-Particule et Cosmologie (APC) (2) LPTMC) Categories: hep-th hep-lat Comments: 23 pages. 24 figures. One suplemental material: Mathematica file with the full expressions of the one-loop Feynman diagrams \\ We consider Yang-Mills theories in a recently proposed family of nonlinear covariant gauges that consistently deals with the issue of Gribov ambiguities. Such gauges provide a generalization of the Curci-Ferrari-Delbourgo-Jarvis gauges which can be formulated as an extremization procedure and might be implemented in numerical calculations. This would allow for nonperturbative studies of Yang-Mills correlators in a broad class of covariant gauges continuously connected to the well studied Landau gauge. We compute the ghost and gluon propagators in the continuum formulation at one-loop order in perturbation theory and we study their momentum dependence down to the deep infrared regime, with and without renormalization group improvement. In particular, we show that the theory admits infrared safe renormalization group trajectories with no Landau pole. Both the gluon and the ghost behave as massive fields at low energy, and the gluon propagator is transverse even away from the Landau gauge limit. We compare our results to those obtained in the usual Curci-Ferrari model, which allows us to pinpoint the specific effects arising from our treatment of Gribov copies. \\ ( http://arxiv.org/abs/1505.07270 , 2030kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07301 Date: Wed, 27 May 2015 13:13:55 GMT (14kb) Title: T-dualization in a curved background in absence of a global symmetry Authors: Lj. Davidovi\'c and B. Sazdovi\'c Categories: hep-th \\ We investigate T-duality of a closed string moving in a weakly curved background of the second order. A previously discussed weakly curved background consisted of a flat metric and a linearly coordinate dependent Kalb-Ramond field with an infinitesimal strength. The background here considered differs from the above in a coordinate dependent metric of a second order. Consequently, the corresponding Ricci tensor is nonzero. As this background does not posses the global shift symmetry the generalized Buscher T-dualization procedure is not applicable to it. We redefine it and make it applicable to backgrounds without the global symmetry. \\ ( http://arxiv.org/abs/1505.07301 , 14kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07353 Date: Wed, 27 May 2015 14:45:13 GMT (326kb) Title: Electromagnetic Casimir effect for conducting plates in de Sitter spacetime Authors: A.

Scr. 90 (2015) 065304 DOI: 10.1088/0031-8949/90/6/065304 \\ Two-point functions, the mean field squared and the vacuum expectation value (VEV) of the energy-momentum tensor are investigated for the electromagnetic field in the geometry of parallel plates on background of $(D+1)$% -dimensional dS spacetime. We assume that the field is prepared in the Bunch-Davies vacuum state and on the plates a boundary condition is imposed that is a generalization of the perfectly conducting boundary condition for an arbitrary number of spatial dimensions. It is shown that for $D\geq 4$ the background gravitational field essentially changes the behavior of the VEVs at separations between the plates larger than the curvature radius of dS spacetime. At large separations, the Casimir forces are proportional to the inverse fourth power of the distance for all values of spatial dimension $D\geq 3$. For $D\geq 4$ this behavior is in sharp contrast with the case of plates in Minkowski bulk where the force decays as the inverse $(D+1)$th power of the distance. \\ ( http://arxiv.org/abs/1505.07353 , 326kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07355 Date: Wed, 27 May 2015 14:47:44 GMT (14kb) Title: Enhancement of hidden symmetries and Chern-Simons couplings Authors: Marc Henneaux and Axel Kleinschmidt and Victor Lekeu Categories: hep-th Comments: To appear in the Proceedings of the 9th Workshop and School on "Quantum Field Theory and Hamiltonian Systems", 24-28 September 2014, Sinaia, Romania \\ We study the role of Chern--Simons couplings for the appearance of enhanced symmetries of Cremmer--Julia type in various theories. It is shown explicitly that for generic values of the Chern--Simons coupling there is only a parabolic Lie subgroup of symmetries after reduction to three space-time dimensions but that this parabolic Lie group gets enhanced to the full and larger Cremmer--Julia Lie group of hidden symmetries if the coupling takes a specific value. This is heralded by an enhanced isotropy group of the metric on the scalar manifold. Examples of this phenomenon are discussed as well as the relation to supersymmetry. Our results are also connected with rigidity theorems of Borel-like algebras. \\ ( http://arxiv.org/abs/1505.07355 , 14kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07357 Date: Wed, 27 May 2015 14:50:14 GMT (111kb,D) Title: Unitarization and Causalization of Non-local quantum field theories by Classicalization Authors: Andrea Addazi Categories: hep-th \\ We suggest that classicalization can cure non-local quantum field theories from acausal divergences in scattering amplitudes, restoring unitarity and causality. In particular, in "trans-non-local" limit, the formation of non-perturbative classical configurations, called {\it classicalons}, in scatterings like $\phi\phi\rightarrow \phi\phi$, can avoid typical acausal divergences. \\ ( http://arxiv.org/abs/1505.07357 , 111kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07379 Date: Wed, 27 May 2015 15:35:45 GMT (37kb,D) Title: Chiral drag force Authors: Krishna Rajagopal, Andrey V. Sadofyev Categories: hep-th hep-ph nucl-th Comments: 28 pages Report-no: MIT-CTP-4676 \\ We provide a holographic evaluation of novel contributions to the drag force acting on a heavy quark moving through strongly interacting plasma. The new contributions are chiral in that they act in opposite directions in plasmas containing an excess of left- or right-handed quarks and in that they are proportional to the coefficient of the axial anomaly. These new contributions to the drag force act either parallel to or antiparallel to an external magnetic field or to the vorticity of the fluid plasma. In all these respects, these contributions to the drag force felt by a heavy quark are analogous to the chiral magnetic effect on light quarks. However, the new contribution to the drag force is independent of the electric charge of the heavy quark and is the same for heavy quarks and antiquarks. We show that although the chiral drag force can be non-vanishing for heavy quarks that are at rest in the local fluid rest frame, it does vanish for heavy quarks that are at rest in a frame in which there is no local entropy current. In this frame, the heavy quark at rest sees counterpropagating momentum and charge currents, both proportional to the axial anomaly coefficient, but feels no drag force. This provides strong concrete evidence for the absence of dissipation in chiral transport, something that has been predicted previously via consideration of symmetries. Along the way to our principal results, we provide a general calculation of the corrections to the drag force due to the presence of gradients in the flowing fluid in the presence of a nonzero chemical potential. We close with a consequence of our result that is at least in principle observable in heavy ion collisions, namely an anticorrelation between the direction of the CME current for light quarks in a given event and the direction of the kick given to the momentum of all the heavy quarks and antiquarks in that event. \\ ( http://arxiv.org/abs/1505.07379 , 37kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07386 Date: Wed, 27 May 2015 15:59:10 GMT (15kb) Title: Space-filling D3-brane within coset approach Authors: S. Bellucci, N. Kozyrev, S. Krivonos, A. Sutulin Categories: hep-th Comments: 12 pages, PACS: 11.30.Pb, 12.60.Jv \\ We derive the component on-shell action of the space-filling D3-brane, {\it i.e.} $N=1$ supersymmetric Born-Infeld action, within the nonlinear realization approach. The covariant Bianchi identity defining the $N=1$, $d=4$ vector supermultiplet has been constructed by introducing a new bosonic Goldstone superfield associated with the generator of the $U(1)$ group, which transforms to each other the spinor generators of unbroken and spontaneously broken $N=1$, $d=4$ supersymmetries. The first component of this Goldstone superfield is the auxiliary field of the vector supermultiplet and, therefore, the Bianchi identity can be properly defined. The component action of the D3-brane has a very simple form, being written in terms of derivatives covariant with respect to spontaneously broken supersymmetry - it just mimics its bosonic counterpart. \\ ( http://arxiv.org/abs/1505.07386 , 15kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07421 Date: Wed, 27 May 2015 18:07:14 GMT (15kb) Title: Sakharov's induced gravity on the AdS background. SM scale as inverse mass parameter of Schwinger-DeWitt expansion Authors: Boris L. Altshuler Categories: hep-th Comments: 21 pages \\ One-loop quantum effective action W of scalar field 'living' on the AdS background of Randall-Sundrum model is defined by now popular way which excludes bulk UV divergencies; thus induced Planck mass is given not by UV regularization parameter like in Sakharov's pioneer work but by the AdS curvature scale. 'Auxiliary mass' method proposed in the paper permits to build the Schwinger-DeWitt expansion of action W. Inverse squared mass parameter of this expansion is determined by the location of the 'visible' brane of RS-model. Obtained expression for the induced vacuum energy density coincides with independently calculated VEV of the stress-energy tensor - in contrast with earlier results of some authors. It is demonstrated that naive equating of values of induced Planck mass and vacuum energy density to those ones of the RS-model determines otherwise arbitrary constants of the model. The Principle of Quantum Self-Consistency is proposed which unifies symbolically Sakharov's approach and bootstrap's "no elementary particle/fields" basic idea. \\ ( http://arxiv.org/abs/1505.07421 , 15kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1505.03070 (*cross-listing*) Date: Tue, 12 May 2015 15:47:25 GMT (10kb) Date (revised v2): Thu, 14 May 2015 12:41:35 GMT (10kb) Title: On the correctness of cosmology from quantum potential Authors: E.

Furthermore, we show that the approach of using a quantum corrected Raychaudhuri equation (QRE), as suggested in arXiv:1404.3093[gr-qc], is unsatisfactory, because, essentially, it uses the Raychaudhuri equation, which is a kinematical equation, in order to predict dynamics. In addition, even within this inconsistent framework, the authors have adopted unjustified assumptions and carried out incorrect steps leading to doubtful conclusions. \\ ( http://arxiv.org/abs/1505.03070 , 10kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07106 (*cross-listing*) Date: Tue, 26 May 2015 20:00:21 GMT (88kb,D) Title: Area Law for Gapless States from Local Entanglement Thermodynamics Authors: Brian Swingle and John McGreevy Categories: cond-mat.str-el hep-th quant-ph Comments: 8 pages, 1 figure \\ We demonstrate an area law bound on the ground state entanglement entropy of a wide class of gapless quantum states of matter using a strategy called local entanglement thermodynamics. The bound depends only on thermodynamic data, actually a single exponent, the hyper-scaling violation exponent $\theta$. All systems in $d$ spatial dimensions obeying our scaling assumptions and with $\theta < d-1$ obey the area law, while systems with $\theta = d-1$ can violate the area law at most logarithmically. We also discuss the case of frustration-free Hamiltonians and show that to violate the area law more than logarithmically these systems must have an unusually large number of low energy states. Finally, we make contact with the recently proposed $s$-source framework and argue that $\theta$ and $s$ are related by $s=2^\theta$. \\ ( http://arxiv.org/abs/1505.07106 , 88kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07272 (*cross-listing*) Date: Tue, 26 May 2015 04:30:06 GMT (33kb) Title: Lanczos-Lovelock gravity from a thermodynamic perspective Authors: Sumanta Chakraborty Categories: gr-qc hep-th Comments: 38 pages, no figures \\ The deep connection between gravitational dynamics and horizon thermodynamics leads to several intriguing features both in general relativity and in Lanczos-Lovelock theories of gravity. Recently in arXiv:1312.3253 several additional results strengthening the above connection have been established within the framework of general relativity. In this work we provide a generalization of the above setup to Lanczos-Lovelock gravity as well. To our expectation it turns out that most of the results obtained in the context of general relativity generalize to Lanczos-Lovelock gravity in a straightforward but non-trivial manner. Another very interesting feature for gravity is that gravitational field equations for arbitrary static and spherically symmetric spacetimes with horizon can be written as a thermodynamic identity in the near horizon limit. This result holds in both general relativity and in Lanczos-Lovelock gravity as well. In a previous work [arXiv:1505.05297] we have shown that, for an arbitrary spacetime, the gravitational field equations near any null surface generically leads to a thermodynamic identity. In this work, we have also generalized this result to Lanczos-Lovelock gravity by showing that gravitational field equations for Lanczos-Lovelock gravity near an arbitrary null surface can be written as a thermodynamic identity. By taking appropriate limit to general relativity we can reproduce the results presented in arXiv:1312.3253 and arXiv:1505.05297. \\ ( http://arxiv.org/abs/1505.07272 , 33kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07330 (*cross-listing*) Date: Wed, 27 May 2015 14:14:33 GMT (23kb) Title: Riemannian curvature of the noncommutative 3-sphere via pseudo-Riemannian calculi Authors: Joakim Arnlind and Mitsuru Wilson Categories: math.QA hep-th math-ph math.MP \\ In order to investigate to what extent the calculus of classical (pseudo-)Riemannian manifolds can be extended to a noncommutative setting, we introduce pseudo-Riemannian calculi of modules over noncommutative algebras. In this framework, it is possible to prove an analogue of Levi-Civita's theorem, stating that there exists at most one torsion-free and metric connection for a given (metric) module, satisfying the requirements of a real metric calculus. Furthermore, the corresponding curvature operator has the same symmetry properties as the classical Riemannian curvature. As our main motivating example, we consider a pseudo-Riemannian calculus over the noncommutative 3-sphere and explicitly determine the torsion-free and metric connection, as well as the curvature operator together with its scalar curvature. \\ ( http://arxiv.org/abs/1505.07330 , 23kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07366 (*cross-listing*) Date: Wed, 27 May 2015 15:14:04 GMT (152kb,D) Title: Single Field Inflation in Supergravity with a $U(1)$ Gauge Symmetry Authors: L. Heurtier, S. Khalil, A. Moursy Categories: hep-ph astro-ph.CO gr-qc hep-th Comments: 16 pages, 2 figures \\ A single field inflation based on a supergravity model with a shift symmetry and $U(1)$ extension of the MSSM is analyzed. We show that one of the real components of the two $U(1)$ charged scalar fields plays the role of inflaton {with} an effective scalar potential similar to the "new chaotic inflation" scenario. Both non-anomalous and anomalous (with Fayet-Iliopoulos term) $U(1)$ are studied. We show that the non-anomalous $U(1)$ scenario is consistent with data of the cosmic microwave background and recent astrophysical measurements. A possible kinetic mixing between $U(1)$ {and} $U(1)_{B-L}$ is considered in order to allow for natural decay channels of the inflaton, leading to a reheating epoch. Upper limits on the reheating temperature thus turn out to favour an intermediate ($\sim {\cal O}(10^{13})$ GeV) scale $B-L$ symmetry breaking. \\ ( http://arxiv.org/abs/1505.07366 , 152kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07371 (*cross-listing*) Date: Wed, 27 May 2015 15:20:09 GMT (453kb,D) Title: Dynamics of the four kinds of Trapping Horizons and Existence of Hawking Radiation Authors: Alexis Helou Categories: gr-qc hep-th Comments: 22 pages, 4 figures \\ We work with the notion of apparent/trapping horizons for spherically symmetric, dynamical spacetimes: these are quasi-locally defined, simply based on the behaviour of congruence of light rays. We show that the sign of the dynamical Hayward-Kodama surface gravity is dictated by the inner/outer nature of the horizon. Using the tunneling method to compute Hawking Radiation, this surface gravity is then linked to a notion of temperature, up to a sign that is dictated by the future/past nature of the horizon. Therefore two sign effects are conspiring to give a positive temperature for the black hole case and the expanding cosmology, whereas the same quantity is negative for white holes and contracting cosmologies. This is consistent with the fact that, in the latter cases, the horizon does not act as a separating membrane, and Hawking emission should not occur. \\ ( http://arxiv.org/abs/1505.07371 , 453kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07388 (*cross-listing*) Date: Wed, 27 May 2015 16:02:30 GMT (614kb,D) Title: Peccei-Quinn Symmetry from Dynamical Supersymmetry Breaking Authors: Keisuke Harigaya, Masahiro Ibe, Kai Schmitz, Tsutomu T. Yanagida Categories: hep-ph hep-th Comments: 46 pages, 2 figures, 1 appendix Report-no: IPMU 15-0075 \\ The proximity of the Peccei-Quinn scale to the scale of supersymmetry breaking in models of pure gravity mediation hints at a common dynamical origin of these two scales. To demonstrate how to make such a connection manifest, we embed the Peccei-Quinn mechanism into the vector-like model of dynamical supersymmetry breaking a la IYIT. Here, we rely on the anomaly-free discrete Z4R symmetry required in models of pure gravity mediation to solve the mu problem to protect the Peccei-Quinn symmetry from the dangerous effect of higher-dimensional operators. This results in a rich phenomenology featuring a QCD axion with a decay constant of O(10^10) GeV and mixed WIMP/axion dark matter. In addition, exactly five pairs of extra 5 and 5* matter multiplets, directly coupled to the supersymmetry breaking sector and with masses close to the gravitino mass, m3/2 ~ 100 TeV, are needed to cancel the Z4R anomalies. \\ ( http://arxiv.org/abs/1505.07388 , 614kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07441 (*cross-listing*) Date: Wed, 27 May 2015 19:28:05 GMT (25kb,D) Title: Can gravitational microlensing by vacuum fluctuations be observed? Authors: S. Carlip Categories: gr-qc hep-th Comments: 8 pages, 1 figure \\ Although the prospect is more plausible than it might appear, the answer to the title question is, unfortunately, "probably not." Quantum fluctuations of vacuum energy can focus light, and while the effect is tiny, the distribution of fluctuations is highly non-Gaussian, offering hope that relatively rare "large" fluctuations might be observable. I show that although gravitational microlensing by such fluctuations become important at scales much larger than the Planck length, the possibility of direct observation remains remote, although there is a small chance that cumulative effects over cosmological distances might be detectable. The effect is sensitive to the size of the Planck scale, however, and could offer a new test of TeV-scale gravity. \\ ( http://arxiv.org/abs/1505.07441 , 25kb) ------------------------------------------------------------------------------ \\ arXiv:1505.07443 (*cross-listing*) Date: Wed, 27 May 2015 19:30:30 GMT (110kb,D) Title: Analytical two-loop soft mass terms of sfermions in Extended GMSB models Authors: Tomasz Jelinski, Janusz Gluza Categories: hep-ph hep-th Comments: 7 pages, 2 figures \\ Analytical two-loop contributions to soft masses of sfermions are derived in Extended GMSB (EGMSB) model with one superpotential coupling between matter and messenger superfields.
