Blanco-Pillado and Benjamin Shlaer Categories: hep-th Comments: 16 pages, 5 figures \\ We construct a simple $5d$ flux compactification stabilized by a complex scalar field winding the extra dimension and demonstrate an instability via nucleation of a bubble of nothing. This occurs when the Kaluza -- Klein dimension degenerates to a point, defining the bubble surface. Because the extra dimension is stabilized by a flux, the bubble surface must be charged, in this case under the axionic part of the complex scalar. This smooth geometry can be seen as a de Sitter topological defect with asymptotic behavior identical to the pure compactification. We discuss how a similar construction can be implemented in more general Freund -- Rubin compactifications. \\ ( http://arxiv.org/abs/1002.4408 , 735kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4411 Date: Wed, 24 Feb 2010 01:47:26 GMT (37kb) Title: Superconformal Sigma Models in Three Dimensions Authors: E. Bergshoeff. S. Cecotti, H. Samtleben and E. Sezgin Categories: hep-th Comments: 39 pages \\ We construct superconformal gauged sigma models with extended rigid supersymmetry in three dimensions. Those with N>4 have necessarily flat targets, but the models with N \leq 4 admit non-flat targets, which are cones with appropriate Sasakian base manifolds. Superconformal symmetry also requires that the three dimensional spacetimes admit conformal Killing spinors which we examine in detail. We present explicit results for the gauged superconformal theories for N=1,2. In particular, we gauge a suitable subgroup of the isometry group of the cone in a superconformal way. We finally show how these sigma models can be obtained from Poincare supergravity. This connection is shown to necessarily involve a subset of the auxiliary fields of supergravity for N \geq 2. \\ ( http://arxiv.org/abs/1002.4411 , 37kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4416 Date: Wed, 24 Feb 2010 18:24:28 GMT (1087kb,D) Title: Fermion correlators in non-abelian holographic superconductors Authors: Steven S. Gubser, Fabio D. Rocha, and Amos Yarom Categories: hep-th Comments: 49 pages, 11 figures Report-no: PUPT-2329 \\ We consider fermion correlators in non-abelian holographic superconductors. The spectral function of the fermions exhibits several interesting features such as support in displaced Dirac cones and an asymmetric distribution of normal modes. These features are compared to similar ones observed in angle resolved photoemission experiments on high T_c superconductors. Along the way we elucidate some properties of p-wave superconductors in AdS_4 and discuss the construction of SO(4) superconductors. \\ ( http://arxiv.org/abs/1002.4416 , 1087kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4431 Date: Tue, 23 Feb 2010 22:20:46 GMT (18kb) Title: Non-Unitary Fermionic Quasinormal Modes at Zero Frequency Authors: Tameem Albash Categories: hep-th Comments: 23 pages \\ We consider the dynamics of a probe fermion charged under a U(1) Maxwell field and a two form potential $B_{(2)}$ in a five dimensional gravity background. The gravity background is constructed from a new solution we find of type IIB supergravity. This new solution is expected to be dual to non-commutative Yang-Mills theory in the 't Hooft limit with global U(1) currents. We study the zero frequency, near horizon behavior of the fermion, where the equations of motion reduce to that of two interacting fermions in AdS$_2$ with an electric field. We show that the operator dimensions in the AdS$_2$ space are complex, leading to the two components of the retarded Green's function in the dual theory to be complex conjugates of each other. In order to preserve unitarity, this result implies there are no zero frequency quasinormal modes in our system. This has important implications for generalizations of recent holographic Fermi liquid setups with AdS$_2$ regions, as it suggests that infinite lifetime excitations can have energies above/below the chemical potential. Therefore, the Fermi energy may not be uniquely set by the chemical potential. Furthermore, since the gravity background breaks rotational symmetry along the spatial directions of the dual Yang-Mills theory, we do not expect the Fermi surface to be spherical in shape in momentum space. \\ ( http://arxiv.org/abs/1002.4431 , 18kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4448 Date: Wed, 24 Feb 2010 04:01:00 GMT (214kb) Title: Lifshitz black holes in the Ho\v{r}ava-Lifshitz gravity Authors: Yun Soo Myung Categories: hep-th Comments: 14 pages, 3 figures \\ We investigate the Lifshitz black holes from the Ho\v{r}ava-Lifshitz gravity by comparing with the Lifshitz black hole from the 3D new massive gravity. We note that these solutions all have single horizons. These black holes are very similar to each other when studying their thermodynamics. It is shown that a second order phase transition is unlikely possible to occur between $z=3,2$ Lifshitz black holes and $z=1$ Ho\v{r}ava black hole. \\ ( http://arxiv.org/abs/1002.4448 , 214kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4449 Date: Wed, 24 Feb 2010 20:28:34 GMT (46kb) Title: Gravity from the extension of spatial diffeomorphisms Authors: Szilard Farkas, Emil J. Martinec Categories: hep-th Comments: 34 pages \\ The possibility of the extension of spatial diffeomorphisms to a larger family of symmetries in a class of classical field theories is studied. The generator of the additional local symmetry contains a quadratic kinetic term and a potential term which can be a general (not necessarily local) functional of the metric. From the perspective of the foundation of Einstein's gravity our results are positive: The extended constraint algebra is either that of Einstein's gravity, or ultralocal gravity. If our goal is a simple modification of Einstein's gravity that for example makes it perturbatively renormalizable, as has recently been suggested, then our results show that there is no such theory within this class. \\ ( http://arxiv.org/abs/1002.4449 , 46kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4484 Date: Wed, 24 Feb 2010 07:17:20 GMT (409kb) Title: Oscillon resonances and creation of kinks in particle collisions Authors: T. Romanczukiewicz, Ya. Shnir Categories: hep-th Comments: 4 pages, 4 figures, revtex4 \\ We present a numerical study of the process of production of kink-antikink pairs in the collision of particle-like states in the one-dimensional $\phi^4$ model. It is shown that there are 3 steps in the process, the first step is to excite the oscillon intermediate state in the particle collision, the second step is a resonance excitation of the oscillon by the incoming perturbations, and finally, the soliton-antisoliton pair can be created from the resonantly excited oscillon. It is shown that the process depends fractally on the amplitude of the perturbations and the wave number of the perturbation. We also present the effective collective coordinate model for this process. \\ ( http://arxiv.org/abs/1002.4484 , 409kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4498 Date: Wed, 24 Feb 2010 09:34:38 GMT (42kb) Title: On The Stability Of Non-Supersymmetric AdS Vacua Authors: Prithvi Narayan and Sandip P. Trivedi Categories: hep-th Comments: 49 pages, LaTex Report-no: TIFR/TH/10-05 \\ We consider two infinite families of Non-Supersymmetric $AdS_4$ vacua, called Type 2) and Type 3) vacua, that arise in massive IIA supergravity with flux. We show that both families are perturbatively stable. We then examine non-perturbative decays of these vacua to other supersymmetric and non-supersymmetric $AdS_4$ vacua mediated by instantons in the thin wall approximation. We find that many decays are ruled out since the tension of the interpolating domain wall is too big compared to the energy difference in AdS units. In fact, within our approximations no decays of Type 2) vacua are allowed, although some decays are only marginally forbidden. This can be understood in terms of a "pairing symmetry" in the landscape which relate Type 2) vacua with supersymmetric ones of the same energy. \\ ( http://arxiv.org/abs/1002.4498 , 42kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4531 Date: Wed, 24 Feb 2010 11:57:12 GMT (23kb) Title: On UV/IR Mixing via Seiberg-Witten Map for Noncommutative QED Authors: Matti Raasakka and Anca Tureanu Categories: hep-th Comments: 16 pages Report-no: HIP-2010-04/TH \\ We consider quantum electrodynamics in noncommutative spacetime by deriving a $\theta$-exact Seiberg-Witten map with fermions in the fundamental representation of the gauge group as an expansion in the coupling constant. Accordingly, we demonstrate the persistence of UV/IR mixing in noncommutative QED with charged fermions via Seiberg-Witten map, extending the results of Schupp and You [1]. \\ ( http://arxiv.org/abs/1002.4531 , 23kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4566 Date: Wed, 24 Feb 2010 15:54:50 GMT (26kb) Title: On instability of Rubakov-Shaposhnikov model Authors: George Lavrelashvili Categories: hep-th Comments: 7 pages, including 1 figure Report-no: AEI-2010-028 \\ Instability of 6 dimensional Rubakov-Shaposhnikov model is reinvestigated.

It is also suggested that gravity and dark energy are types of the quantum entanglement force, similar to Verlinde's entropic force. If the entanglement entropy of the universe saturates the Bekenstein bound, this gives holographic dark energy with the equation of state consistent with current observational data. This connection between quantum information and gravity gives some new insights on the origin of gravity, dark energy, the holographic principle and arrow of time. \\ ( http://arxiv.org/abs/1002.4568 , 40kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4580 Date: Wed, 24 Feb 2010 16:51:10 GMT (26kb) Title: The Moduli Space Metric for Well-Separated Non-Abelian Vortices Authors: Toshiaki Fujimori, Giacomo Marmorini, Muneto Nitta, Keisuke Ohashi, Norisuke Sakai Categories: hep-th Comments: 31 pages \\ The moduli space metric and its Kahler potential for well-separated non-Abelian vortices are obtained in U(N) gauge theories with N Higgs fields in the fundamental representation. \\ ( http://arxiv.org/abs/1002.4580 , 26kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4613 Date: Wed, 24 Feb 2010 20:15:34 GMT (42kb,D) Title: On correlation functions of operators dual to classical spinning string states Authors: Romuald A. Janik, Piotr Surowka, Andrzej Wereszczynski Categories: hep-th Comments: 27 pages, 3 figures \\ We explore how to compute, classically at strong coupling, correlation functions of local operators corresponding to classical spinning string states. The picture we obtain is of `fattened' Witten diagrams, the evaluation of which turns out to be surprisingly subtle and requires a modification of the naive classical action due to a necessary projection onto appropriate wave functions. We examine string solutions which compute the simplest case of a two-point function and reproduce the right scaling with the anomalous dimensions corresponding to the energies of the associated spinning string solutions. We also describe, under some simplifying assumptions, how the spacetime dependence of a conformal three-point correlation function arises in this setup. \\ ( http://arxiv.org/abs/1002.4613 , 42kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1002.3836 (*cross-listing*) Date: Fri, 19 Feb 2010 22:47:24 GMT (7kb) Title: BF gravity with Immirzi parameter and cosmological constant Authors: Merced Montesinos, Mercedes Velazquez Categories: gr-qc hep-th Comments: 4 pages, no figures, LaTeX file Journal-ref: Phys.Rev.D81:044033,2010 DOI: 10.1103/PhysRevD.81.044033 \\ The action principle of the BF type introduced by Capovilla, Montesinos, Prieto, and Rojas (CMPR) which describes general relativity with Immirzi parameter is modified in order to allow the inclusion of the cosmological constant. The resulting action principle is on the same footing as the original Plebanski action in the sense that the equations of motion coming from the new action principle are equivalent to the Holst action principle plus a cosmological constant without the need of imposing additional restrictions on the fields. We consider this result a relevant step towards the coupling of matter fields to gravity in the framework of the CMPR action principle. \\ ( http://arxiv.org/abs/1002.3836 , 7kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4120 (*cross-listing*) Date: Mon, 22 Feb 2010 14:08:45 GMT (1313kb) Title: Self-Relative (or Machian) Information: Entropy-Area Relation Authors: Nima Khosravi Categories: gr-qc hep-th \\ The entropy-area relation of black holes is one of the important results of theoretical physics. It is one of the few relations that is used to test theories of quantum gravity in the absence of any experimental evidence. It states that $4 \times \ell_P^2$ is the fundamental area that holds \textit{one} bit of information. Consequently, a question arises: why $4 \times \ell_P^2$ and not $1 \times \ell_P^2$ is the fundamental holder of \textit{one} bit of information? In any case it seems the latter choice is more natural. We show that this question can be answered with a more explicit counting of the independent states of a black hole. To do this we introduce a method of counting which we name self-relative information. It says that a bit alone does not have any information unless it is considered near other bits. Utilizing this approach we obtain the correct entropy-area relation for black holes with $1 \times \ell_P^2$ as the fundamental holder of \textit{one} bit of information. This method also predicts, naturally, the existence of logarithmic corrections to the entropy-area relation. \\ ( http://arxiv.org/abs/1002.4120 , 1313kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4230 (*cross-listing*) Date: Tue, 23 Feb 2010 07:31:00 GMT (171kb) Title: A Couple of Issues Concerning Spinor Dark Energy Authors: Hao Wei Categories: gr-qc astro-ph.CO hep-ph hep-th Comments: 15 pages, 2 figures, revtex4 \\ Recently, the so-called Elko spinor field has been proposed to be a candidate of dark energy. It is a non-standard spinor and has unusual properties. When the Elko spinor field is used in cosmology, its unusual properties could bring some interesting consequences. In the present work, we consider two different issues concerning the dark energy model described by the Elko spinor fields. Firstly, we discuss the cosmological coincidence problem in the spinor dark energy model by using the dynamical system method. Our results show that the coincidence problem should be taken to heart in the investigations of spinor dark energy models. Next, we turn to another issue. In this work, we propose a simple method to reconstruct spinor dark energy from the cosmological observations. We find that this reconstruction method works fairly well. \\ ( http://arxiv.org/abs/1002.4230 , 171kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4265 (*cross-listing*) Date: Tue, 23 Feb 2010 08:33:38 GMT (669kb) Title: D-branes in Bose-Einstein Condensates Authors: Kenichi Kasamatsu, Hiromitsu Takeuchi, Muneto Nitta, Makoto Tsubota Categories: cond-mat.quant-gas hep-ph hep-th Comments: 5 pages, 2 figures \\ We demonstrate theoretically that wall-vortex composite solitons, which are analogues of D-brane in string theory, can be realized in rotating phase-separated two-component Bose-Einstein condensates and that they are experimentally observable.

We systematically study the underlying polynomials and characterize the motion of test particles by its zeros. Since the presence of the "Misner string" in the Taub-NUT metric has led to different interpretations, we consider these in terms of the geodesics of the space-time. In particular, we address the geodesic incompleteness at the horizons discussed by Misner and Taub, and the analytic extension of Miller, Kruskal and Godfrey, and compare with the Reissner-Nordstr\"om space-time. \\ ( http://arxiv.org/abs/1002.4342 , 2635kb) ------------------------------------------------------------------------------ \\ arXiv:1002.4353 (*cross-listing*) Date: Tue, 23 Feb 2010 15:30:29 GMT (16kb) Title: Unusual Corrections to Scaling in Entanglement Entropy Authors: John Cardy, Pasquale Calabrese Categories: cond-mat.stat-mech hep-th quant-ph Comments: 15 pages, no figures \\ We present a general theory of the corrections to the asymptotic behaviour of the Renyi entropies which measure the entanglement of an interval A of length L with the rest of an infinite one-dimensional system, in the case when this is described by a conformal field theory of central charge c. These can be due to bulk irrelevant operators of scaling dimension x>2, in which case the leading corrections are of the expected form L^{-2(x-2)} for values of n close to 1. However for n>x/(x-2) corrections of the form L^{2-x-x/n} and L^{-2x/n} arise and dominate the conventional terms. We also point out that the last type of corrections can also occur with x less than 2. They arise from relevant operators induced by the conical space-time singularities necessary to describe the reduced density matrix. These agree with recent analytic and numerical results for quantum spin chains. We also compute the effect of marginally irrelevant bulk operators, which give a correction (log L)^{-2}, with a universal amplitude. We present analogous results for the case when the interval lies at the end of a semi-infinite system. \\ ( http://arxiv.org/abs/1002.4353 , 16kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:0805.1009 replaced with revised version Tue, 23 Feb 2010 23:58:05 GMT (25kb) Title: Comparing two approaches to the K-theory classification of D-branes Authors: Fabio Ferrari Ruffino and Raffaele Savelli Categories: hep-th math-ph math.KT math.MP Comments: 33 pages, no figures \\ ( http://arxiv.org/abs/0805.1009 , 25kb) ------------------------------------------------------------------------------ \\ arXiv:0906.1482 (*cross-listing*) replaced with revised version Wed, 24 Feb 2010 10:14:28 GMT (20kb) Title: A new current algebra and the reflection equation Authors: P.
