Comp\`ere, K. Hajian, A. Seraj and M.M. Sheikh-Jabbari Categories: hep-th gr-qc Comments: 5 pages \\ We construct the NHEG phase space, the classical phase space of Near-Horizon Extremal Geometries with fixed angular momenta and entropy, and with the largest symmetry algebra. We focus on vacuum solutions to $d$ dimensional Einstein gravity. Each element in the phase space is a geometry with $SL(2,R)\times U(1)^{d-3}$ Killing isometries which has vanishing $SL(2,R)$ and constant $U(1)$ charges. We construct an on-shell vanishing symplectic structure, which leads to an infinite set of symplectic symmetries. In four spacetime dimensions, the phase space is unique and the symmetry algebra consists of the familiar Virasoro algebra, while in $d > 4$ dimensions the symmetry algebra, the NHEG algebra, contains infinitely many Virasoro subalgebras. The nontrivial central term of the algebra is proportional to the black hole entropy. This phase space and in particular its symmetries might serve as a basis for a semiclassical description of extremal rotating black hole microstates. \\ ( http://arxiv.org/abs/1503.07861 , 13kb) ------------------------------------------------------------------------------ \\ arXiv:1503.07883 Date: Thu, 26 Mar 2015 20:04:01 GMT (742kb) Title: Spectral zeta function and non-perturbative effects in ABJM Fermi-gas Authors: Yasuyuki Hatsuda Categories: hep-th math-ph math.MP Comments: 32 pages, 4 figures \\ The exact partition function in ABJM theory on three-sphere can be regarded as a canonical partition function of a non-interacting Fermi-gas with an unconventional Hamiltonian. All the information on the partition function is encoded in the discrete spectrum of this Hamiltonian. We explain how (quantum mechanical) non-perturbative corrections in the Fermi-gas system appear from a spectral consideration. Basic tools in our analysis are a Mellin-Barnes type integral representation and a spectral zeta function. From a consistency with known results, we conjecture that the spectral zeta function in the ABJM Fermi-gas has an infinite number of "non-perturbative" poles, which are invisible in the semi-classical expansion of the Planck constant. We observe that these poles indeed appear after summing up perturbative corrections. As a consequence, the perturbative resummation of the spectral zeta function causes non-perturbative corrections to the grand canonical partition function. We also present another example associated with a spectral problem in topological string theory. A conjectured non-perturbative free energy on the resolved conifold is successfully reproduced in this framework. \\ ( http://arxiv.org/abs/1503.07883 , 742kb) ------------------------------------------------------------------------------ \\ arXiv:1503.07886 Date: Thu, 26 Mar 2015 20:27:53 GMT (37kb,D) Title: The Geometry of Supermanifolds and New Supersymmetric Actions Authors: L. Castellani, R. Catenacci, and P. A. Grassi Categories: hep-th Comments: LateX2e, 51 pages \\ We construct the Hodge dual for supermanifolds by means of the Grassmannian Fourier transform of superforms. In the case of supermanifolds it is known that the superforms are not sufficient to construct a consistent integration theory and that the integral forms are needed. They are distribution-like forms which can be integrated on supermanifolds as a top form can be integrated on a conventional manifold. In our construction of the Hodge dual of superforms they arise naturally. The compatibility between Hodge duality and supersymmetry is exploited and applied to several examples. We define the irreducible representations of supersymmetry in terms of integral and superforms in a new way which can be easily generalised to several models in different dimensions. The construction of supersymmetric actions based on the Hodge duality is presented and new supersymmetric actions with higher derivative terms are found. These terms are required by the invertibility of the Hodge operator. \\ ( http://arxiv.org/abs/1503.07886 , 37kb) ------------------------------------------------------------------------------ \\ arXiv:1503.07900 Date: Thu, 26 Mar 2015 21:07:18 GMT (11kb) Title: Universal spin-1/2 fermion field localization on a 5D braneworld Authors: Nandinii Barbosa-Cendejas, Dagoberto Malag\'on-Morej\'on and Refugio Rigel Mora-Luna Categories: hep-th Comments: 7 pages MSC-class: 00A79 \\ In this work we present a refined method for the localization of spin-$\frac{1}{2}$ fermions on the 5D braneworld paradigm. We begin by proposing a more natural ansatz for the Yukawa coupling in the 5D bulk fermionic action, that guarantees the localization of the ground states for the 4D fermions with right or left chirality. Furthermore, we show that the fermion ground states localization allow us to show the absence of tachyonic modes in the left and right-chiral Kaluza-Klein mass spectrum. More precisely, we show that localization of gravity in the 5D braneworld implies the localization of the spin-$\frac{1}{2}$ fermions. \\ ( http://arxiv.org/abs/1503.07900 , 11kb) ------------------------------------------------------------------------------ \\ arXiv:1503.07909 Date: Thu, 26 Mar 2015 21:31:58 GMT (374kb,D) Title: Cosmological Attractors from $\alpha$-Scale Supergravity Authors: Diederik Roest, Marco Scalisi Categories: hep-th astro-ph.CO gr-qc hep-ph Comments: 5 pages, 3 figures \\ The Planck value of the spectral index can be interpreted as $n_s = 1 - 2/N$ in terms of the number of e-foldings $N$. An appealing explanation for this phenomenological observation is provided by $\alpha$-attractors: the inflationary predictions of these supergravity models are fully determined by the curvature of the Kahler manifold. We provide a novel formulation of $\alpha$-attractors which only involves a single chiral superfield. Our construction involves a natural deformation of no-scale models, and employs these to construct a De Sitter plateau with an exponential fall-off. Finally, we show how analogous structures with a flat Kahler geometry arise as a singular limit of such $\alpha$-scale models. \\ ( http://arxiv.org/abs/1503.07909 , 374kb) ------------------------------------------------------------------------------ \\ arXiv:1503.07912 Date: Thu, 26 Mar 2015 21:45:12 GMT (48kb,D) Title: Winding out of the Swamp: Evading the Weak Gravity Conjecture with F-term Winding Inflation? Authors: Arthur Hebecker, Patrick Mangat, Fabrizio Rompineve and Lukas T. Witkowski Categories: hep-th astro-ph.CO Comments: 8 pages, 1 figure \\ We present a new model of large field inflation along a winding trajectory in the field space of two axionic fields, where the 'axions' originate from the complex structure moduli sector of a Calabi-Yau 3-fold at large complex structure. The winding trajectory arises from fixing one combination of axions by bulk fluxes and allows for a transplanckian effective field range. The inflaton potential arises from small 'instantonic' corrections to the geometry and realises natural inflation. By working in a regime of large complex structure for two complex structure moduli the inflaton potential can be made subdominant without severe tuning. We also discuss the impact of the recent 'no-go theorems' for transplanckian axion periodicities on our work. Interestingly, our setup seems to realise a loophole pointed out in arXiv:1503.04783: our construction is a candidate for a string theory model of large field inflation which is consistent with the mild form of the weak gravity conjecture for axions. \\ ( http://arxiv.org/abs/1503.07912 , 48kb) ------------------------------------------------------------------------------ \\ arXiv:1503.07934 Date: Fri, 27 Mar 2015 00:45:06 GMT (12kb) Title: Ferminoic Casimir effect between spheres Authors: L. P. Teo Categories: hep-th Comments: 14 pages \\ We consider the Casimir interaction between two spheres corresponding to massless Dirac fields with MIT-bag boundary conditions. Using operator approach, we derive the TGTG-formula for the Casimir interaction energy between the two spheres. A byproduct is the explicit formula for the translation matrix that relates the fermionic spherical waves in different coordinate systems. In the large separation limit, it is found that the order of the Casimir interaction energy is $L^{-5}$, where $L$ is the separation between the centers of the spheres. This order is intermediate between that of two Dirichlet spheres (of order $L^{-3}$) and two Neumann spheres (of order $L^{-7}$). In the small separation limit, we derive analytically the asymptotic expansion of the Casimir interaction energy up to the next-to-leading order term. The leading term agrees with the proximity force approximation. The result for the next-to-leading order term is compared to the corresponding results for scalar fields and electromagnetic fields. \\ ( http://arxiv.org/abs/1503.07934 , 12kb) ------------------------------------------------------------------------------ \\ arXiv:1503.07950 Date: Fri, 27 Mar 2015 02:58:55 GMT (10kb) Title: On Coupling NEC-Violating Matter to Gravity Authors: Saugata Chatterjee, Maulik Parikh, and Jan Pieter van der Schaar Categories: hep-th astro-ph.CO gr-qc Comments: 11 pages, LaTeX \\ We show that effective theories of matter that classically violate the null energy condition cannot be minimally coupled to Einstein gravity without being inconsistent with both string theory and black hole thermodynamics.

New particles with masses comparable to the Hubble scale produce a distinctive signature on the non-gaussianities. This feature arises in the squeezed limit of the correlation functions of primordial fluctuations. It consists of particular power law, or oscillatory, behavior that contains information about the masses of new particles. There is an angular dependence that gives information about the spin. We also have a relative phase that crucially depends on the quantum mechanical nature of the fluctuations and can be viewed as arising from the interference between two processes. While some of these features were noted before in the context of specific inflationary scenarios, here we give a general description emphasizing the role of symmetries in determining the final result. \\ ( http://arxiv.org/abs/1503.08043 , 1883kb) ------------------------------------------------------------------------------ \\ arXiv:1503.08062 Date: Fri, 27 Mar 2015 13:18:48 GMT (64kb) Title: Construction and exact solution of a nonlinear quantum field model in quasi-higher dimension Authors: Anjan Kundu Categories: hep-th math-ph math.MP Comments: 8 pages, 1 figure, Latex \\ Nonperturbative exact solutions are allowed for quantum integrable models in one space-dimension. Going beyond this class we propose an alternative Lax matrix approach, exploiting the hidden multi-time concept in integrable systems and construct a novel quantum nonlinear Schr\"odinger model in quasi-two dimensions. An intriguing field commutator is discovered, confirming the integrability of the model and yielding its exact Bethe ansatz solution with rich scattering and bound-state properties. The universality of the scheme is expected to cover diverse models, opening up a new direction in the field. \\ ( http://arxiv.org/abs/1503.08062 , 64kb) ------------------------------------------------------------------------------ \\ arXiv:1503.08130 Date: Fri, 27 Mar 2015 16:25:26 GMT (31kb,D) Title: Riding Gravity Away from Doomsday Authors: Ashoke Sen Categories: hep-th astro-ph.CO gr-qc Comments: LaTeX file, 8 pages, prepared for 2015 essay competition of gravity research foundation \\ The discovery that most of the energy density in the universe is stored in the form of dark energy has profound consequences for our future. In particular our current limited understanding of quantum theory of gravity indicates that some time in the future our universe will undergo a phase transition that will destroy us and everything else around us instantaneously. However the laws of gravity also suggest a way out -- some of our descendants could survive this catastrophe by riding gravity away from the danger. In this essay I describe the tale of this escape from doomsday. \\ ( http://arxiv.org/abs/1503.08130 , 31kb) ------------------------------------------------------------------------------ \\ arXiv:1503.08136 Date: Fri, 27 Mar 2015 16:41:49 GMT (28kb,D) Title: Instanton operators and symmetry enhancement in 5d supersymmetric USp, SO and exceptional gauge theories Authors: Gabi Zafrir Categories: hep-th Comments: 34 pages \\ We study the fermionic zero modes around 1 instanton operators for 5d supersymmetric gauge theories of type USp, SO and the exceptional groups.

Beccaria and A.A. Tseytlin Categories: hep-th Comments: 34 pages Report-no: Imperial-TP-AT-2015-01 \\ We observe that the partition function of the set of all free massless higher spins s=0,1,2,3,... in flat space is equal to one: the ghost determinants cancel against the "physical" ones or, equivalently, the (regularized) total number of degrees of freedom vanishes. This reflects large underlying gauge symmetry and suggests analogy with supersymmetric or topological theory. The Z=1 property extends also to the AdS background, i.e. the 1-loop vacuum partition function of Vasiliev theory is equal to 1 (assuming a particular regularization of the sum over spins); this was noticed earlier as a consistency requirement for the vectorial AdS/CFT duality. We find that Z=1 is also true in the conformal higher spin theory (with higher-derivative d^{2s} kinetic terms) expanded near flat or conformally flat S^4 background. We also consider the partition function of free conformal theory of symmetric traceless rank s tensor field which has 2-derivative kinetic term but only scalar gauge invariance in flat space. This non-unitary theory has Weyl-invariant action in curved background and is an example of a "partially massless" field in conformally flat space. We discuss in detail the special case of s=2 (or "conformal graviton"), compute the corresponding conformal anomaly coefficients and compare them with previously found expressions for generic representations of conformal group in 4 dimensions. \\ ( http://arxiv.org/abs/1503.08143 , 51kb) ------------------------------------------------------------------------------ \\ arXiv:1503.08161 Date: Fri, 27 Mar 2015 17:32:30 GMT (103kb,D) Title: Scrambling time from local perturbations of the eternal BTZ black hole Authors: Pawe{\l} Caputa, Joan Sim\'on, Andrius \v{S}tikonas, Tadashi Takayanagi and Kento Watanabe Categories: hep-th Comments: 37 pages, 5 figures \\ We compute the mutual information between finite intervals in two non-compact 2d CFTs in the thermofield double formulation after one of them has been locally perturbed by a primary operator at some time $t_\omega$ in the large $c$ limit. We determine the time scale, called the scrambling time, at which the mutual information vanishes and the original entanglement between the thermofield double gets destroyed by the perturbation. We provide a holographic description in terms of a free falling particle in the eternal BTZ black hole that exactly matches our CFT calculations. Our results hold for any time $t_\omega$. In particular, when the latter is large, they reproduce the bulk shock-wave propagation along the BTZ horizon description. \\ ( http://arxiv.org/abs/1503.08161 , 103kb) ------------------------------------------------------------------------------ \\ arXiv:1503.08183 Date: Fri, 27 Mar 2015 18:52:16 GMT (26kb) Title: Taub-NUT and Dynamical Systems : the geometric connection demystified Authors: Sumanto Chanda, Partha Guha and Raju Roychowdhury Categories: hep-th gr-qc math-ph math.MP Comments: 2+30 pages \\ A short analysis of the curvature of the Taub-NUT tells us if it truly is a gravitational instanton, followed up by a brief review of its other geometrical properties. We follow this up with a comparison to Bertrand spacetime and computation of its conserved quantities. Such quantities reflect on its symmetries expressed through Killing tensors, like the Killing St\"ackel and Yano tensors. We will attempt to describe an easy procedure to derive the spatial Killing-Yano tensors from the conserved quantities and examine the possibility of a graded Lie-algebra structure via Schouten-Nijenhuis brackets. Finally we will derive the related hyperk\"ahler structures and compare them with the Killing-Yano tensors of Taub-NUT. \\ ( http://arxiv.org/abs/1503.08183 , 26kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1503.07857 (*cross-listing*) Date: Thu, 26 Mar 2015 00:52:57 GMT (18kb) Title: Regular Black Holes in $f(T)$ Gravity Authors: Ednaldo L.

Wetterich Categories: gr-qc astro-ph.CO hep-th Comments: 35 pages, 6 figures \\ Does the observable spectrum of cosmic fluctuations depend on detailed initial conditions? This addresses the question if the general inflationary paradigm is sufficient to predict within a given model the spectrum and amplitude of cosmic fluctuations, or if additional particular assumptions about the initial conditions are needed. The answer depends on the number of e-foldings $N_{in}$ between the beginning of inflation and horizon crossing of the observable fluctuations. We discuss an interacting inflaton field in an arbitrary homogeneous and isotropic geometry, employing the quantum effective action $\Gamma$. An exact time evolution equation for the correlation function involves the second functional derivative $\Gamma^{(2)}$. The operator formalism and quantum vacua for interacting fields are not needed. Use of the effective action also allows one to address the change of frames by field transformations (field relativity). For not too large $N_{in}$ we find that memory of the initial conditions is preserved. In this case the cosmic microwave background cannot disentangle between the initial spectrum and its processing at horizon crossing. The inflaton potential cannot be reconstructed without assumptions about the initial state of the universe. We argue that for very large $N_{in}$ a universal scaling form of the correlation functions is reached. This can be due to symmetrization and equilibration effects not yet contained in our approximation, which drive the short distance tail of the correlation function towards the Lorentz invariant propagator in flat space. \\ ( http://arxiv.org/abs/1503.07860 , 422kb) ------------------------------------------------------------------------------ \\ arXiv:1503.08198 (*cross-listing*) Date: Fri, 27 Mar 2015 19:37:47 GMT (10kb) Title: Classification of Commutator Algebras Leading to the New Type of Closed Baker-Campbell-Hausdorff Formulas Authors: Marco Matone Categories: math-ph hep-th math.MP math.RT quant-ph Comments: 18 pages \\ We show that there are thirteen {\it Types} of commutator algebras leading to the new closed forms of the Baker-Campbell-Hausdorff (BCH) formula $$e^Xe^Z=e^{aX+bZ+c[X,Z]+dI} \ , $$ derived in arXiv:1502.06589, and holding also in cases when $[X,Z]$ includes elements different from $X$ and $Z$. This follows by a rescaled version of the decomposition $e^Xe^Ye^Z=e^Xe^{\alpha Y} e^{1-\alpha Y} e^Z$, with $\alpha$ fixed in such a way that it reduces to the exponential product $e^{\tilde X}e^{\tilde Y}$ satisfying the Van-Brunt and Visser condition $[\tilde X,\tilde Y]=\tilde u\tilde X+\tilde v\tilde Y+\tilde cI$. It turns out that $x:=e^\alpha$ satisfies, in the generic case, the algebraic equation $$ x^{u+z}-x^u e^{z-w}-x^z e^v+e^{v-w+z}=0 \ , $$ where $u,v,w$ and $z$ are the parameters in the commutators $[X,Y]=uX+vY+cI$, $[Y,Z]=wY+ zZ+ d I$. We find all the equations that characterize the solution of the above decomposition problem by combining it with the Jacobi Identity. \\ ( http://arxiv.org/abs/1503.08198 , 10kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1010.5792 replaced with revised version Fri, 27 Mar 2015 15:03:20 GMT (82kb) Title: Fivebrane instantons, topological wave functions and hypermultiplet moduli spaces Authors: Sergei Alexandrov, Daniel Persson, Boris Pioline Categories: hep-th Comments: 73 pages; v3: minor corrections Journal-ref: JHEP 1103:111,2011 DOI: 10.1007/JHEP03(2011)111 \\ ( http://arxiv.org/abs/1010.5792 , 82kb) ------------------------------------------------------------------------------ \\ arXiv:1110.0466 replaced with revised version Fri, 27 Mar 2015 15:10:48 GMT (1018kb,D) Title: Wall-crossing, Rogers dilogarithm, and the QK/HK correspondence Authors: Sergei Alexandrov, Daniel Persson, Boris Pioline Categories: hep-th math-ph math.AG math.DG math.MP math.SG Comments: 67 pages, 1 figure, v2: references [22-26] added, significant correction in sec 2.2.2, cosmetic changes elsewhere, published version; v3: minor corrections Report-no: L2C:11-165, CERN-PH-TH-2011-239 Journal-ref: JHEP 1112 (2011) 027 DOI: 10.1007/JHEP12(2011)027 \\ ( http://arxiv.org/abs/1110.0466 , 1018kb) ------------------------------------------------------------------------------ \\ arXiv:1304.0766 replaced with revised version Fri, 27 Mar 2015 15:14:45 GMT (44kb) Title: Quantum hypermultiplet moduli spaces in N=2 string vacua: a review Authors: Sergei Alexandrov, Jan Manschot, Daniel Persson, Boris Pioline Categories: hep-th Comments: 31 pages; Contribution to the Proceedings of String Math 2012; v2: references added, misprints corrected, published version \\ ( http://arxiv.org/abs/1304.0766 , 44kb) ------------------------------------------------------------------------------ \\ arXiv:1404.7631 (*cross-listing*) replaced with revised version Fri, 27 Mar 2015 07:50:46 GMT (27kb) Title: Entropy bounds and field equations Authors: Alessandro Pesci Categories: gr-qc hep-th Comments: 8 pages, 1 figure; the contents are the same but, in an attempt to strengthen the exposition and make it clearer, the paper is changed in many respects, including the naming and subdivision of the sections, and the title \\ ( http://arxiv.org/abs/1404.7631 , 27kb) ------------------------------------------------------------------------------ \\ arXiv:1406.2360 replaced with revised version Fri, 27 Mar 2015 15:22:27 GMT (19kb) Title: $R^3$ index for four-dimensional $N=2$ field theories Authors: Sergei Alexandrov, Gregory W.
