In the presence of a suitably strong magnetic field, the dynamics of fermions in the bulk is effectively reduced from four to two dimensions. These two-dimensional fermions can subsequently be treated using the techniques of bosonization and the difficult many-body problem of building a gravitating, charged quantum star is reduced to solving the sine-Gordon model coupled to a gauge field and a metric. The kinks of the sine-Gordon model provide the holographic dual of the lowest Landau levels of the strongly-coupled d=2+1 dimensional boundary field theory. The system exhibits order one oscillations in the magnetic susceptibility, now arising as a classical effect in the bulk. Moreover, as the chemical potential is varied, we find jumps in the charge density, oscillations in the fractionalised charge density and plateaux in the cohesive charge density \\ ( http://arxiv.org/abs/1208.5771 , 621kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5773 Date: Tue, 28 Aug 2012 20:00:37 GMT (23kb) Title: A Covariant Master Theory for Novel Galilean Invariant Models and Massive Gravity Authors: Gregory Gabadadze, Kurt Hinterbichler, Justin Khoury, David Pirtskhalava, Mark Trodden Categories: hep-th gr-qc Comments: 27 pages Report-no: UCSD-PTH-12-11 \\ Coupling the galileons to a curved background has been a tradeoff between maintaining second order equations of motion, maintaining the galilean shift symmetries, and allowing the background metric to be dynamical. We propose a construction which can achieve all three for a novel class of galilean invariant models, by coupling a scalar with the galilean symmetry to a massive graviton. This generalizes the brane construction for galileons, by adding to the brane a dynamical metric, (non-universally) interacting with the galileon field. Alternatively, it can be thought of as an extension of the ghost-free massive gravity, or as a massive graviton-galileon scalar-tensor theory. In the decoupling limit of these theories, new kinds of galileon invariant interactions arise between the scalar and the longitudinal mode of the graviton. These have higher order equations of motion and infinite powers of the field, yet are ghost-free. \\ ( http://arxiv.org/abs/1208.5773 , 23kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5884 Date: Wed, 29 Aug 2012 11:41:27 GMT (211kb) Title: The gauge structure of generalised diffeomorphisms Authors: David S. Berman, Martin Cederwall, Axel Kleinschmidt and Daniel C. Thompson Categories: hep-th Comments: 24 pp., plain tex, 1 figure Report-no: QMUL-PH-12-14; AEI-2012-085 \\ We investigate the generalised diffeomorphisms in M-theory, which are gauge transformations unifying diffeomorphisms and tensor gauge transformations. After giving an En(n)-covariant description of the gauge transformations and their commutators, we show that the gauge algebra is infinitely reducible, i.e., the tower of ghosts for ghosts is infinite. The Jacobiator of generalised diffeomorphisms gives such a reducibility transformation. We give a concrete description of the ghost structure, and demonstrate that the infinite sums give the correct (regularised) number of degrees of freedom. The ghost towers belong to the sequences of rep- resentations previously observed appearing in tensor hierarchies and Borcherds algebras. All calculations rely on the section condition, which we reformulate as a linear condition on the cotangent directions. The analysis holds for n < 8. At n = 8, where the dual gravity field becomes relevant, the natural guess for the gauge parameter and its reducibility still yields the correct counting of gauge parameters. \\ ( http://arxiv.org/abs/1208.5884 , 211kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5902 Date: Wed, 29 Aug 2012 12:57:45 GMT (8kb) Title: Analytic study of holographic superconductors with non-linear electrodynamics Authors: Rabin Banerjee, Sunandan Gangopadhyay, Dibakar Roychowdhury, Arindam Lala Categories: hep-th cond-mat.supr-con gr-qc Comments: Latex, 6 pages \\ In this paper, we have analytically studied the properties of the s-wave holographic superconductors in the planar Schwarzschild-AdS background. Using the Sturm-Liouville eigenvalue problem we have been able to calculate the critical temperature for condensation in terms of the charge density. This is a continuation and eventual culmination of the work begun in \cite{Sun2}. The results obtained analytically agree well with the numerical findings\cite{hs19}. \\ ( http://arxiv.org/abs/1208.5902 , 8kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5935 Date: Wed, 29 Aug 2012 14:46:46 GMT (28kb) Title: Brane Resolution Through Fibration Authors: Justin F. Vazquez-Poritz and Zhibai Zhang Categories: hep-th Comments: 35 pages \\ We consider p-branes with one or more circular directions fibered over the transverse space. The fibration, in conjunction with the transverse space having a blown-up cycle, enables these p-brane solutions to be completely regular. Some such circularly-wrapped D3-brane solutions describe flows from SU(N)^3 N=2 theory, F_0 theory, as well as an infinite family of superconformal quiver gauge theories, down to three-dimensional field theories. We discuss the operators that are turned on away from the UV fixed points. Similarly, there are wrapped M2-brane solutions which describe smooth flows from known three-dimensional supersymmetric Chern-Simons matter theories, such as ABJM theory. We also consider p-brane solutions on gravitational instantons, and discuss various ways in which U-duality can be applied to yield other non-singular solutions. \\ ( http://arxiv.org/abs/1208.5935 , 28kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5948 Date: Wed, 29 Aug 2012 15:43:07 GMT (16kb) Title: Renormalization of the Nonlinear O(3) Model with Theta-Term Authors: Raphael Flore Categories: hep-th Comments: 11 pages \\ The renormalization of the topological term in the two-dimensional nonlinear O(3) model is studied by means of the Functional Renormalization Group. By considering the topological charge as a limit of a more general operator, it is shown that a finite multiplicative renormalization occurs in the extreme infrared. In order to compute the effects of the zero modes, a specific representation of the Clifford algebra is developed which allows to reformulate the bosonic problem in terms of Dirac operators and to employ the index theorem. \\ ( http://arxiv.org/abs/1208.5948 , 16kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5971 Date: Wed, 29 Aug 2012 17:21:49 GMT (23kb) Title: Partition Function on the Five-torus and for the Fivebrane on S^1XT^5 Authors: Louise Dolan and Yang Sun Categories: hep-th Comments: 28 pages \\ We compute the partition function of five-dimensional abelian gauge theory on a five-torus T5 with a general flat metric using the Dirac method of quantizing with constraints. We compare this with the partition function of a single fivebrane compactified on S1 times T5, which is obtained from the six-torus calculation of Dolan and Nappi. The radius R1 of the circle S1 is set to the dimensionful gauge coupling constant g^2= R1. \\ ( http://arxiv.org/abs/1208.5971 , 23kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5975 Date: Wed, 29 Aug 2012 17:41:43 GMT (584kb) Title: Gravitational wave signal from massive gravity Authors: A. Emir Gumrukcuoglu, Sachiko Kuroyanagi, Chunshan Lin, Shinji Mukohyama, Norihiro Tanahashi Categories: hep-th astro-ph.CO gr-qc Comments: 22 pages, 6 figures Report-no: IPMU12-0164 \\ We discuss the detectability of gravitational waves with a time dependent mass contribution, by means of the stochastic gravitational wave observations. Such a mass term typically arises in the cosmological solutions of massive gravity theories. We conduct the analysis based on a general quadratic action, and thus the results apply universally to any massive gravity theories in which modification of general relativity appears primarily in the tensor modes. The primary manifestation of the modification in the gravitational wave spectrum is a sharp peak. The position and height of the peak carry information on the present value of the mass term, as well as the duration of the inflationary stage. We also discuss the detectability of such a gravitational wave signal using the future-planned gravitational wave observatories. \\ ( http://arxiv.org/abs/1208.5975 , 584kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5979 Date: Wed, 29 Aug 2012 18:20:53 GMT (25kb) Title: Beyond LLM in M-theory Authors: Eoin \'O Colg\'ain Categories: hep-th Comments: 1+30 pages \\ The Lin, Lunin, Maldacena (LLM) ansatz in D = 11 supports two independent Killing directions when a general Killing spinor ansatz is considered. Here we show that these directions always commute, identify when the Killing spinors are charged, and show that both their inner product and resulting geometry are governed by two fundamental constants. In particular, setting one constant to zero leads to AdS7 x S4, setting the other to zero gives AdS4 x S7, while flat spacetime is recovered when both these constants are zero. Furthermore, when the constants are equal, the spacetime is either LLM, or it corresponds to the Kowalski-Glikman solution where the constants are simply the mass parameter. \\ ( http://arxiv.org/abs/1208.5979 , 25kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5994 Date: Wed, 29 Aug 2012 19:09:58 GMT (14kb) Title: Extending the Belavin-Knizhnik "wonderful formula" by the characterization of the Jacobian Authors: Marco Matone Categories: hep-th math.AG Comments: 13 pages \\ A long-standing question in string theory is to find the explicit expression of the bosonic measure, a crucial issue also in determining the superstring measure. Such a measure was known up to genus three. Belavin and Knizhnik conjectured an expression for genus four which has been recently proved in the framework of the recently introduced vector-valued Teichmueller modular forms. It turns out that for g>3 the bosonic measure is expressed in terms of such forms. In particular, the genus four Belavin-Knizhnik "wonderful formula" has a remarkable extension to arbitrary genus whose structure is deeply related to the characterization of the Jacobian locus. Furthermore, it turns out that the bosonic string measure has an elegant geometrical interpretation as generating the quadrics in P^{g-1} characterizing the Riemann surface. All this leads to identify forms on the Siegel upper half-space that, if certain conditions related to the characterization of the Jacobian are satisfied, express the bosonic measure as a multiresidue in the Siegel upper half-space. We also suggest that it may exist a super analog on the super Siegel half-space. \\ ( http://arxiv.org/abs/1208.5994 , 14kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5999 Date: Wed, 29 Aug 2012 19:30:41 GMT (25kb) Title: Adinkras and SUSY Holography Authors: S.

We show that the assumption of point-like source leads to a divergence of the renormalized energy densities at the position of the source and analyze in detail the structure of such singularity in terms of a delta function and its derivatives. We then consider the case of an extended source, smeared out over a finite volume and described by an appropriate form factor, and show that in this case all divergences in the local energy densities are removed. Our results for the structure of the divergences in the field energy densities also resolve an apparent inconsistency between the vacuum expectation value of the field Hamiltonian and of the field energy densities integrated over all space. \\ ( http://arxiv.org/abs/1208.5478 , 12kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5777 (*cross-listing*) Date: Tue, 28 Aug 2012 20:04:11 GMT (10kb) Title: Creation of the universe with a stealth scalar field Authors: Hideki Maeda and Kei-ichi Maeda Categories: gr-qc hep-th Comments: 5 pages Report-no: CECS-PHY-12/06 \\ The stealth scalar field is a non-trivial configuration without any back-reaction to geometry, which is characteristic for non-minimally coupled scalar fields. Studying the creation probability of the de Sitter universe with a stealth scalar field by the Hartle and Hawking's semi-classical method, we show that the effect of the stealth field can be significant. For the class of scalar fields we consider, creation of the universe with a stealth field is possible for a discrete value of the coupling constant and its creation rate is almost the same as that of the universe in vacuum. \\ ( http://arxiv.org/abs/1208.5777 , 10kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5789 (*cross-listing*) Date: Tue, 28 Aug 2012 20:49:34 GMT (174kb,D) Title: Two-brane system in a vacuum bulk with a single equation of state Authors: Juan L.

To appear in Scientific Reports (NPG) \\ We investigate the nature of correlations in Gaussian light sources used for ghost imaging. We adopt methods from quantum information theory to distinguish genuinely quantum from classical correlations. Combining a microscopic analysis of speckle-speckle correlations with an effective coarse-grained description of the beams, we show that quantum correlations exist even in `classical'-like thermal light sources, and appear relevant for the implementation of ghost imaging in the regime of low illumination. We further demonstrate that the total correlations in the thermal source beams effectively determine the quality of the imaging, as quantified by the signal-to-noise ratio. \\ ( http://arxiv.org/abs/1208.5808 , 1669kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5822 (*cross-listing*) Date: Wed, 29 Aug 2012 01:54:25 GMT (8kb) Title: An operator-theoretical treatment of the Maskawa-Nakajima equation in the massless abelian gluon model Authors: Shuji Watanabe Categories: math.FA hep-ph hep-th math-ph math.MP Comments: 11 pages MSC-class: 45P05, 47H10, 81T13 \\ The Maskawa-Nakajima equation has attracted considerable interest in elementary particle physics. From the viewpoint of operator theory, we study the Maskawa-Nakajima equation in the massless abelian gluon model. On the basis of the Schauder fixed-point theorem, we first show that there is a nonzero solution to the Maskawa-Nakajima equation when the parameter $\lambda$ satisfies $\lambda>2$. Moreover, we show that the solution is infinitely differentiable and strictly decreasing. We thus conclude that the massless abelian gluon model exhibits the spontaneous chiral symmetry breaking when $\lambda>2$. On the basis of the Banach fixed-point theorem, we next show that there is a unique solution 0 to the Maskawa-Nakajima equation when $0<\lambda<1$, from which we conclude that the model realizes the chiral symmetry when $0<\lambda<1$. \\ ( http://arxiv.org/abs/1208.5822 , 8kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5859 (*cross-listing*) Date: Wed, 29 Aug 2012 08:39:55 GMT (6kb) Title: RG Invariance of the Pole Mass in the Minimal Subtraction Scheme Authors: Chungku Kim Categories: hep-ph hep-th \\ We prove the renormalization group(RG) invariance of the pole mass with respect to the RG functions of the minimal subtraction(MS) scheme and illustrate this in case of the the neutral scalar field theory both in the symmetric and in the broken symmetry phase. \\ ( http://arxiv.org/abs/1208.5859 , 6kb) ------------------------------------------------------------------------------ \\ arXiv:1208.5974 (*cross-listing*) Date: Wed, 29 Aug 2012 17:32:40 GMT (352kb,D) Title: Landau meets Newton: time translation symmetry breaking in classical mechanics Authors: Liu Zhao, Wei Xu and Pengfei Yu Categories: gr-qc hep-th Comments: 10 pages, 1 figure \\ Every classical Newtonian mechanical system can be equipped with a nonstandard Hamiltonian structure, in which the Hamiltonian is the square of the canonical Hamiltonian up to a constant shift, and the Poisson bracket is nonlinear. In such a formalism, time translation symmetry can be spontaneously broken, provided the potential function becomes negative. A nice analogy between time translation symmetry breaking and the Landau theory of second order phase transitions is established, together with several example cases illustrating time translation breaking ground states. In particular, the $\Lambda$CDM model of FRW cosmology is reformulated as the time translation symmetry breaking ground states. \\ ( http://arxiv.org/abs/1208.5974 , 352kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1106.5410 replaced with revised version Wed, 29 Aug 2012 04:39:31 GMT (155kb,D) Title: Tinkertoys for the D_N series Authors: Oscar Chacaltana and Jacques Distler Categories: hep-th Comments: 53 pages, 268 figures, LaTeX2e, utarticle class.
