Pando Zayas, Ignacio Salazar Landea, Antonello Scardicchio Categories: hep-th cond-mat.dis-nn cond-mat.str-el cond-mat.supr-con Comments: 26 pages, 10 figures Report-no: MCTP-14-16, MPP-2014-311 \\ We implement the effects of disorder on a holographic p-wave superconductor by introducing a random chemical potential which defines the local energy of the charge carriers. Since there are various possibilities for the orientation of the vector order parameter, we explore the behavior of the condensate in the parallel and perpendicular directions to the introduced disorder. We clarify the nature of various branches representing competing solutions and construct the disordered phase diagram. We find that moderate disorder enhances superconductivity as determined by the value of the condensate. The disorder we introduce is characterized by its spectral properties, and we also study its influence on the spectral properties of the condensate and charge density. We find fairly universal responses of the resulting power spectra characterized by linear functions of the disorder power spectrum. \\ ( http://arxiv.org/abs/1407.7526 , 991kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7540 Date: Mon, 28 Jul 2014 20:00:29 GMT (29kb,D) Title: The Euler current and parity odd transport Authors: Siavash Golkar, Matthew M. Roberts, Dam T. Son Categories: hep-th cond-mat.mes-hall Comments: 24 pages \\ For a spacetime of odd dimensions endowed with a unit vector field, we introduce a new topological current that is identically conserved and whose charge is equal to the Euler character of the even dimensional spacelike foliations. The existence of this current allows us to introduce new Chern-Simons-type terms in the effective field theories describing relativistic quantum Hall states and (2+1) dimensional superfluids. Using effective field theory, we calculate various correlation functions and identify transport coefficients. In the quantum Hall case, this current provides the natural relativistic generalization of the Wen-Zee term, required to characterize the shift and Hall viscosity in quantum Hall systems. For the superfluid case this term is required to have nonzero Hall viscosity and to describe superfluids with non s-wave pairing. \\ ( http://arxiv.org/abs/1407.7540 , 29kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7542 Date: Mon, 28 Jul 2014 20:00:56 GMT (46kb,D) Title: Generalised geometry for string corrections Authors: Andr\'e Coimbra, Ruben Minasian, Hagen Triendl and Daniel Waldram Categories: hep-th math.DG Comments: 49 pages Report-no: CERN-PH-TH/2014-138, Imperial/TP/2014/DW/03, IPhT-t14/105, ITP-UH-12/14 \\ We present a general formalism for incorporating the string corrections in generalised geometry, which necessitates the extension of the generalised tangent bundle. Not only are such extensions obstructed, string symmetries and the existence of a well-defined effective action require a precise choice of the (generalised) connection. The action takes a universal form given by a generalised Lichnerowitz--Bismut theorem. As examples of this construction we discuss the corrections linear in $\alpha'$ in heterotic strings and the absence of such corrections for type II theories. \\ ( http://arxiv.org/abs/1407.7542 , 46kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7575 Date: Mon, 28 Jul 2014 21:32:26 GMT (15kb) Title: Conformal Higgs Inflation Authors: Ichiro Oda and Takahiko Tomoyose Categories: hep-th gr-qc hep-ph Comments: 13 pages Report-no: DPUR/TH/41 \\ We investigate a locally scale-invariant (that is, Weyl-invariant) theory which describes the coupling of gravity and the standard model from the viewpont of the Higgs mechanism and inflation. It is shown that this theory exhibits a peculiar feature of a coupling between the gauge field and the inflaton in a large field limit whereas it nicely describes the standard model coupled to general relativity in a small field limit. Moreover, we discuss a possibility that this Weyl invariant theory could explain the recent BICEP2 measurement by deforming the potential term in an appropriate way, and find it to be difficult to do that even if we introduce a non-analytical type of the potential. \\ ( http://arxiv.org/abs/1407.7575 , 15kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7580 Date: Mon, 28 Jul 2014 21:50:00 GMT (250kb,D) Title: De Sitter Vacua from a D-term Generated Racetrack Uplift Authors: Markus Rummel and Yoske Sumitomo Categories: hep-th Comments: 20 pages, 1 figure Report-no: KEK-TH-1755 \\ We propose an uplift mechanism using a structure of multi-K\"ahler moduli dependence in the F-term potential of type IIB string theory compactifications. This mechanism requires a D-term condition that fixes one modulus to be proportional to another modulus, resulting in a trivial D-term potential. De Sitter minima are realized along with an enhancement of the volume in the Large Volume Scenario and no additional suppression of the uplift term such as warping is required. We further show the possibility to realize the uplift mechanism in the presence of more K\"ahler moduli such that we expect the uplift mechanism to work in many other compactifications. \\ ( http://arxiv.org/abs/1407.7580 , 250kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7608 Date: Tue, 29 Jul 2014 00:27:28 GMT (18kb) Title: Chiral anomaly for V-A fields in four- and six-dimensional curved space Authors: S.

Kluson Categories: hep-th Comments: 13 pages \\ This paper is devoted to the analysis of the integrability of D1-brane on group manifold. We consider D1-brane as principal chiral model, determine corresponding equations of motions and find Lax connection. Then we calculate the Poisson brackets of Lax connection and we find that it has similar structure as in case of principal chiral model. As the second example we consider more general background with non-zero NS-NS two form. We again show that D1-brane theory is integrable on this background and determine Poisson brackets of Lax connection. \\ ( http://arxiv.org/abs/1407.7665 , 28kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7692 Date: Tue, 29 Jul 2014 11:13:27 GMT (1209kb) Title: Modified natural inflation in the light of BICEP2 Authors: Debaprasad Maity and Pankaj Saha Categories: hep-th gr-qc Comments: 28 pages, 7 figures \\ In this paper we explored in detail a phenomenological model of modified single field natural inflation in the light of recent cosmological experiments BICEP2. Our main goal is to construct an inflationary model which not only predicts the important cosmological quantities such as $(n_s, r)$ compatible with the experimental observation but also is consistent with the low energy effective theory framework. Therefore, all the fundamental scale apart from $M_p$ and quantities of our interest should be within the sub-Planckian region. In order to achieve our goal we modify the usual single field natural inflationary model by a specific form of higher derivative kinetic term called kinetic gravity braiding (KGB). One of our guiding principles to construct such a model is the constant shift symmetry of the axion. We have chosen the form of the KGB term in such a way that it predicts the required value of $n_s\simeq 0.96$ and a large tensor to scalar ratio $r> 0.1$. Importantly for a wide range of parameter space our model has sub-Planckian axion decay constant $f$ and the scale of inflation $\Lambda$. However, the reheating after the end of inflation limits the value of $f$ so that we are unable to get $f$ to be significantly lower than $M_p$. Furthermore, we find sub-Planckian field excursion for the axion field $\Delta \phi \simeq f$ for the sufficient number of e-folding ${\cal N} \gtrsim 50 $. We also discussed in detail about the natural preheating mechanism in our model based on the recently proposed Chern-Simons coupling. We found this gravity mediated preheating is very difficult to achieve in our model. With our general analytic argument, we also would like to emphasize that Chern-Simons mediated preheating is very unlikely to happen in any slow roll inflationary model. \\ ( http://arxiv.org/abs/1407.7692 , 1209kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7721 Date: Tue, 29 Jul 2014 13:32:38 GMT (33kb) Title: Compact Formulas for the Completed Mock Modular Forms Authors: Tohru Eguchi and Yuji Sugawara Categories: hep-th math-ph math.MP Comments: 1+31 pages, no figure \\ In this paper we present a new compact expression of the elliptic genus of SL(2)/U(1)-supercoset theory by making use of the `spectral flow method' of the path-integral evaluation. This new expression is written in a form like a Poincare series with a non-holomorphic Gaussian damping factor, and manifestly shows the modular and spectral flow properties of a real analytic Jacobi form. As a related problem, we present similar compact formulas for the modular completions of various mock modular forms which appear in the representation theory of N=2,4 superconformal algebras. We further discuss the generalization to the cases of arbitrary spin-structures, that is, the world-sheet fermions with twisted boundary conditions parameterized by a continuous parameter. This parameter is naturally identified with the `u-variable' in the Appell-Lerch sum. \\ ( http://arxiv.org/abs/1407.7721 , 33kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7730 Date: Tue, 29 Jul 2014 14:10:41 GMT (28kb,D) Title: General coordinate invariance in quantum many-body systems Authors: Tomas Brauner and Solomon Endlich and Alexander Monin and Riccardo Penco Categories: hep-th cond-mat.str-el hep-ph Comments: 14 pages \\ We extend the notion of general coordinate invariance to many-body, not necessarily relativistic, systems. As an application, we investigate nonrelativistic general covariance in Galilei-invariant systems. The peculiar transformation rules for the background metric and gauge fields, first introduced by Son and Wingate in 2005 and refined in subsequent works, follow naturally from our framework. Our approach makes it clear that Galilei or Poincare symmetry is by no means a necessary prerequisite for making the theory invariant under coordinate diffeomorphisms. General covariance merely expresses the freedom to choose spacetime coordinates at will, whereas the true, physical symmetries of the system can be separately implemented as "internal" symmetries within the vielbein formalism. A systematic way to implement such symmetries is provided by the coset construction. We illustrate this point by applying our formalism to nonrelativistic s-wave superfluids. \\ ( http://arxiv.org/abs/1407.7730 , 28kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7735 Date: Tue, 29 Jul 2014 14:21:02 GMT (14kb) Title: Real Baum-Connes assembly and T-duality for torus orientifolds Authors: Jonathan Rosenberg Categories: hep-th math.KT math.OA Comments: 13 pages MSC-class: 46L60 (Primary) 19K35 19L64 81T30 46L85 19L50 (Secondary) \\ We show that the real Baum-Connes conjecture for abelian groups, possibly twisted by a cocycle, explains the isomorphisms of (twisted) KR-groups that underlie all T-dualities of torus orientifold string theories. \\ ( http://arxiv.org/abs/1407.7735 , 14kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7744 Date: Tue, 29 Jul 2014 14:52:00 GMT (1004kb,D) Title: Galileons and strong gravity Authors: Javier Chagoya, Kazuya Koyama, Gustavo Niz, Gianmassimo Tasinato Categories: hep-th astro-ph.CO gr-qc Comments: 24 pages, 11 figures \\ In the context of a cubic Galileon model in which the Vainshtein mechanism suppresses the scalar field interactions with matter, we study low-density stars with slow rotation and static relativistic stars. We develop an expansion scheme to find approximated solutions inside the Vainshtein radius, and show that deviations from General Relativity (GR), while considering rotation, are also suppressed by the Vainshtein mechanism. In a quadratic coupling model, in which the scalarisation effect can significantly enhance deviations from GR in normal scalar tensor gravity, the Galileon term successfully suppress the large deviations away from GR. Moreover, using a realistic equation of state, we construct solutions for a relativistic star, and show that deviations from GR are more suppressed for higher density objects. However, we found that the scalar field solution ceases to exist above a critical density, which roughly corresponds to the maximum mass of a neutron star. This indicates that, for a compact object described by a polytropic equation of state, the configuration that would collapse into a black hole cannot support a non-trivial scalar field. \\ ( http://arxiv.org/abs/1407.7744 , 1004kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7756 Date: Tue, 29 Jul 2014 15:35:10 GMT (33kb) Title: Quantum effects in topological and Schwarzschild de Sitter brane: Aspects of torsion on ${\mathbf{(D{\bar D})_4}}$-brane universe Authors: Richa Kapoor, Supriya Kar and Deobrat Singh Categories: hep-th gr-qc hep-ph Comments: 29 pages, 3 figures \\ We investigate an effective torsion curvature in a second order formalism underlying a two form world-volume dynamics in a $D_5$-brane. In particular, we consider the two form in presence of a background (open string) metric in a $U(1)$ gauge theory. Interestingly the formalism may be viewed via a non-coincident pair of $(D{\bar D})_5$-brane with a global NS two form on an anti brane and a local two form on a brane. The energy-momentum tensor is computed in the six dimensional CFT. It is shown to source a metric fluctuation on a vacuum created pair of $(D{\bar D})_4$-brane at a cosmological horizon by the two form quanta in the gauge theory. The emergent gravity scenario is shown to describe a low energy (perturbative) string vacuum in $6D$ with a (non-perturbative) quantum correction by a lower ($p<5$) dimensional $D_p$ brane or an anti brane in the formalism. A closed string exchange between a pair of $(D{\bar D})_4$-brane, underlying a closed/open string duality, is argued to describe the Einstein vacuum in a low energy limit. We obtain topological de Sitter and Schwarzschild brane universe in six dimensions. The brane/anti-brane geometries are analyzed to explore some of their characteristic and thermal behaviours in presence of the quantum effects. They reveal an underlying nine dimensional type IIA and IIB superstring theories on $S^1$. \\ ( http://arxiv.org/abs/1407.7756 , 33kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7777 Date: Tue, 29 Jul 2014 17:07:45 GMT (16kb) Title: Jumps and twists in affine Toda field theories Authors: Anastasia Doikou Categories: hep-th math-ph math.MP nlin.SI Comments: 19 pages, Latex \\ The concept of point-like "jump" defects is investigated in the context of affine Toda field theories. The Hamiltonian formulation is employed for the analysis of the problem. The issue is also addressed when integrable boundary conditions ruled by the classical twisted Yangian are present. In both periodic and boundary cases explicit expressions of conserved quantities as well as the relevant Lax pairs and sewing conditions are extracted. It is also observed that in the case of the twisted Yangian the bulk behavior is not affected by the presence of the boundaries. \\ ( http://arxiv.org/abs/1407.7777 , 16kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7815 Date: Tue, 29 Jul 2014 18:34:21 GMT (17kb) Title: Relation between large dimension operators and oscillator algebra of Young diagrams Authors: Hai Lin Categories: hep-th math-ph math.MP Comments: 21 pages \\ The operators with large scaling dimensions can be labelled by Young diagrams. Among other bases, the operators using restricted Schur polynomials have been known to have a large $N$ but nonplanar limit under which they map to states of a system of harmonic oscillators. We analyze the oscillator algebra acting on pairs of long rows or long columns in the Young diagrams of the operators. The oscillator algebra can be reached by a Inonu-Wigner contraction of the $u(2)$ algebra inside of the $u(p)$ algebra of $p$ giant gravitons. We present evidences that integrability in this case can persist at higher loops due to the presence of the oscillator algebra which is expected to be robust under loop corrections in the nonplanar large $N$ limit. \\ ( http://arxiv.org/abs/1407.7815 , 17kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7816 Date: Tue, 29 Jul 2014 18:35:39 GMT (38kb,D) Title: Renyi entropy, stationarity, and entanglement of the conformal scalar Authors: Jeongseog Lee, Aitor Lewkowycz, Eric Perlmutter, Benjamin R. Safdi Categories: hep-th cond-mat.stat-mech quant-ph Comments: 37 pages \\ We extend previous work on the perturbative expansion of the Renyi entropy, $S_q$, around $q=1$ for a spherical entangling surface in a general CFT. Applied to conformal scalar fields in various spacetime dimensions, the results appear to conflict with the known conformal scalar Renyi entropies. On the other hand, the perturbative results agree with known Renyi entropies in a variety of other theories, including theories of free fermions and vector fields and theories with Einstein gravity duals. We propose a resolution stemming from a careful consideration of boundary conditions near the entangling surface. This is equivalent to a proper treatment of total-derivative terms in the definition of the modular Hamiltonian. As a corollary, we are able to resolve an outstanding puzzle in the literature regarding the Renyi entropy of ${\cal N}=4$ super-Yang-Mills near $q=1$. A related puzzle regards the question of stationarity of the renormalized entanglement entropy (REE) across a circle for a (2+1)-dimensional massive scalar field. We point out that the boundary contributions to the modular Hamiltonian shed light on the previously-observed non-stationarity. Moreover, IR divergences appear in perturbation theory about the massless fixed point that inhibit our ability to reliably calculate the REE at small non-zero mass. \\ ( http://arxiv.org/abs/1407.7816 , 38kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7836 Date: Tue, 29 Jul 2014 19:29:48 GMT (19kb) Title: Scattering equations and BCJ relations for gauge and gravitational amplitudes with massive scalar particles Authors: Stephen G.

To this end we use the perturbative static potential at the presently best known accuracy, i.e. up to ${\cal O}(\alpha_s^4)$, in momentum space. The lattice potential is computed on a fine lattice with $a \approx 0.042 \, \textrm{fm}$ in position space. To allow for a comparison and matching of both results, the lattice potential is transformed into momentum space by means of a discrete Fourier transform. The value of $\Lambda_{\bar{\textrm{MS}}}^{(n_f=2)}$ is extracted in momentum space. All sources of statistical and systematic errors are discussed. The uncertainty in the value of $\Lambda_{\bar{\textrm{MS}}}^{(n_f=2)}$ is found to be smaller than that obtained in a recent position space analysis of the static potential based on the same lattice data. Our final results are $r_0\Lambda_{\bar{\textrm{MS}}}^{(n_f=2)} = 0.692(31)$ and $\Lambda_{\bar{\textrm{MS}}}^{(n_f=2)} = 331(21) \, \textrm{MeV}$. \\ ( http://arxiv.org/abs/1407.7503 , 403kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7606 (*cross-listing*) Date: Tue, 29 Jul 2014 00:13:07 GMT (35kb) Title: A Generalization of the Functional Calculus of Observables and Notion of Joint Measurability to the Case of Non-commuting Observables Authors: Richard DeJonghe, Kimberly Frey, Tom Imbo Categories: quant-ph hep-th math-ph math.MP \\ For any pair of bounded observables $A$ and $B$ with pure point spectra, we construct an associated "joint observable" which gives rise to a notion of a joint (projective) measurement of $A$ and $B$, and which conforms to the intuition that one can measure non-commuting observables simultaneously, provided one is willing to give up arbitrary precision. As an application, we show how our notion of a joint observable naturally allows for a construction of a "functional calculus," so that for any pair of observables $A$ and $B$ as above, and any (Borel measurable) function $f: \mathbb{R}^2 \rightarrow \mathbb{R}$, a new "generalized observable" $f(A,B)$ is obtained. Moreover, we show that this new functional calculus has some rather remarkable properties. \\ ( http://arxiv.org/abs/1407.7606 , 35kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7742 (*cross-listing*) Date: Tue, 29 Jul 2014 14:42:57 GMT (14kb) Title: Cosmological singleton gravity theory and dS/LCFT correspondence Authors: Yun Soo Myung and Taeyoon Moon Categories: gr-qc hep-th Comments: 1+16 pages, no figures \\ We study the evolution of cosmological perturbations generated during de Sitter inflation in the singleton gravity theory.

N. Lobo, Prado Martin-Moruno Categories: gr-qc astro-ph.CO hep-th Comments: 24 pages, 7 figures \\ We consider novel wormhole solutions supported by a matter content that minimally violates the null energy condition. More specifically, we consider an equation of state in which the sum of the energy density and radial pressure is proportional to a constant with a value smaller than that of the inverse area characterising the system, i.e., the area of the wormhole mouth. This approach is motivated by a recently proposed cosmological event, denoted "the little sibling of the big rip", where the Hubble rate and the scale factor blow up but the cosmic derivative of the Hubble rate does not [1]. By using the cut-and-paste approach, we match interior spherically symmetric wormhole solutions to an exterior Schwarzschild geometry, and analyze the stability of the thin-shell to linearized spherically symmetric perturbations around static solutions, by choosing suitable properties for the exotic material residing on the junction interface radius. Furthermore, we also consider an inhomogeneous generalisation of the equation of state considered above and analyse the respective stability regions. In particular, we obtain a specific wormhole solution with an asymptotic behaviour corresponding to a global monopole. \\ ( http://arxiv.org/abs/1407.7758 , 1869kb) ------------------------------------------------------------------------------ \\ arXiv:1407.7761 (*cross-listing*) Date: Tue, 29 Jul 2014 15:52:28 GMT (50kb,D) Title: Effective string theory and the long-range relativistic corrections to the quark-antiquark potential Authors: Nora Brambilla, Michael Groher, Hector E. Martinez, Antonio Vairo Categories: hep-ph hep-lat hep-th Comments: 22 pages, 7 figures Report-no: TUM-EFT 36/12 \\ The complete expression of the heavy quark-antiquark potential up to order $1/m^2$ is known from QCD in terms of Wilson loop expectation values. We use that expression and a mapping, assumed to be valid at large distances, between Wilson loop expectation values and correlators evaluated in the effective string theory, to compute the potential. We obtain previously unknown results for the spin and momentum-independent parts of the potential. They may be interpreted as relativistic corrections to the string tension, $\sigma$, effectively reducing it by an amount $9\,\zeta_3/(2\pi^3) \times (\sigma/m)^2$ in the equal mass case. We confirm known results for the other parts of the potential.

Theor. Exp. Phys. 023E02, (2014)}, where the extra degrees of freedom enter through the spatial dependence of the gauge transformation function $T_0(r,t)\backsim t+A(r)$. Written in this form, the Vainshtein mechanism is a way to recover the Birkhoff theorem for scales near the source and the Cosmic no-hair conjecture for scales near the cosmological horizon. Additionally, the Vainshtein mechanism is the dual version of the particle creation process in a black-Hole (radiation). Then if we want to analyze the Hawking radiation inside dRGT, we have to be careful when some apparent extra contribution appears. This extra contribution comes from the dual version of the Vainshtein mechanism, behaving as a particle creation process from the point of view of an observer located at scales $r>>r_V$, with $r_V$ being the Vainshtein scale. \\ ( http://arxiv.org/abs/1407.7796 , 68kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1112.5165 (*cross-listing*) replaced with revised version Tue, 29 Jul 2014 12:42:30 GMT (0kb,I) Title: Finite volume analysis of scattering theory in the scaling Potts model Authors: Gabor Takacs Categories: cond-mat.stat-mech hep-th Comments: Superseded by arXiv preprint 1405.3157 Report-no: ITP-Budapest Report No. 655 \\ ( http://arxiv.org/abs/1112.5165 , 0kb) ------------------------------------------------------------------------------ \\ arXiv:1201.4544 (*cross-listing*) replaced with revised version Tue, 29 Jul 2014 05:17:48 GMT (157kb) Title: Dark Energy with Logarithmic Cosmological Fluid Authors: Seyen Kouwn, Phillial Oh Categories: gr-qc astro-ph.CO hep-th Comments: 14 pages, 1 figure, to be published in The Journal of the Korean Physical Society \\ ( http://arxiv.org/abs/1201.4544 , 157kb) ------------------------------------------------------------------------------ \\ arXiv:1307.0243 (*cross-listing*) replaced with revised version Mon, 28 Jul 2014 21:18:35 GMT (35kb) Title: Form factors in sinh- and sine-Gordon models, deformed Virasoro algebra, Macdonald polynomials and resonance identities Authors: Michael Lashkevich and Yaroslav Pugai (Landau Inst. and MIPT) Categories: math-ph hep-th math.MP nlin.SI Comments: 29 pages, no figures; v2: (2.47), (3.5) corrected; v3: miscorrected (2.47) reverted; references corrected; v4: misprints and negligible mistakes corrected; references updated; v5: for so long unnoticed mistake in (2.50) corrected DOI: 10.1016/j.nuclphysb.2013.10.013 \\ ( http://arxiv.org/abs/1307.0243 , 35kb) ------------------------------------------------------------------------------ \\ arXiv:1311.1092 (*cross-listing*) replaced with revised version Tue, 29 Jul 2014 16:04:50 GMT (617kb,D) Title: Stable Extensions with(out) Gravity Authors: Oleg Antipin, Jens Krog, Matin Mojaza, Francesco Sannino Categories: hep-ph hep-th Comments: 12 pages, 4 figures Report-no: CP3-Origins-2013-44, DIAS-2013-44 Journal-ref: Nuclear Physics, Section B (2014), pp. 125-134 DOI: 10.1016/j.nuclphysb.2014.06.023 \\ ( http://arxiv.org/abs/1311.1092 , 617kb) ------------------------------------------------------------------------------ \\ arXiv:1311.7227 (*cross-listing*) replaced with revised version Tue, 29 Jul 2014 01:15:18 GMT (2216kb,D) Title: A superasymptotic formula for the number of plane partitions Authors: Suresh Govindarajan (IITM) and Naveen S.
