To this end, we solve the classical string on three T-dual toroidal backgrounds: a torus with H-flux, a twisted torus and a non-geometric background with Q-flux. In all three situations we work under the assumption of a dilute flux and consider quantities to linear order in the flux density. Furthermore, we perform the first steps of a canonical quantization for the twisted torus, to derive commutators of the string expansion modes. We use them as well as T-duality to determine, in the non-geometric background, a commutator of two string coordinates, which turns out to be non-vanishing. We relate this non-commutativity to the closed string boundary conditions, and the non-geometric Q-flux. \\ ( http://arxiv.org/abs/1211.6437 , 48kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6442 Date: Tue, 27 Nov 2012 21:01:00 GMT (2701kb,D) Title: Torsional Anomalies, Hall Viscosity, and Bulk-boundary Correspondence in Topological States Authors: Taylor L. Hughes, Robert G. Leigh, and Onkar Parrikar Categories: hep-th cond-mat.mes-hall Comments: 59 pages, 6 figures \\ We study the transport properties of topological insulators, encoding them in a generating functional of gauge and gravitational sources. Much of our focus is on the simple example of a free massive Dirac fermion, the so-called Chern insulator, especially in 2+1 dimensions. In such cases, when parity and time-reversal symmetry are broken, it is necessary to consider the gravitational sources to include a frame and an independent spin connection with torsion. In 2+1 dimensions, the simplest parity-odd response is the Hall viscosity. We compute the Hall viscosity of the Chern insulator using a careful regularization scheme, and find that although the Hall viscosity is generally divergent, the difference in Hall viscosities of distinct topological phases is well-defined and determined by the mass gap. Furthermore, on a 1+1-dimensional edge between topological phases, the jump in the Hall viscosity across the interface is encoded, through familiar anomaly inflow mechanisms, in the structure of anomalies. In particular, we find new torsional contributions to the covariant diffeomorphism anomaly in 1+1 dimensions. Including parity-even contributions, we find that the renormalized generating functionals of the two topological phases differ by a chiral gravity action with a negative cosmological constant. This (non-dynamical) chiral gravity action and the corresponding physics of the interface theory is reminiscent of well-known properties of dynamical holographic gravitational systems. Finally, we consider some properties of spectral flow of the edge theory driven by torsional dislocations. \\ ( http://arxiv.org/abs/1211.6442 , 2701kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6461 Date: Tue, 27 Nov 2012 21:51:12 GMT (62kb,D) Title: Dissipation in the effective field theory for hydrodynamics: First order effects Authors: Solomon Endlich, Alberto Nicolis, Rafael A. Porto, Junpu Wang Categories: hep-th Comments: 14 pages, 1 figure \\ We introduce dissipative effects in the effective field theory of hydrodynamics. We do this in a model-independent fashion by coupling the long-distance degrees of freedom explicitly kept in the effective field theory to a generic sector that "lives in the fluid", which corresponds physically to the microscopic constituents of the fluid. At linear order in perturbations, the symmetries, the derivative expansion, and the assumption that this microscopic sector is thermalized, allow us to characterize the leading dissipative effects at low frequencies via three parameters only, which correspond to bulk viscosity, shear viscosity, and--in the presence of a conserved charge--heat conduction. Using our methods we re-derive the Kubo relations for these transport coefficients. \\ ( http://arxiv.org/abs/1211.6461 , 62kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6529 Date: Wed, 28 Nov 2012 06:36:51 GMT (1807kb) Title: Non-perturbative effects and Yukawa hierarchies in F-theory SU(5) Unification Authors: Anamar\'ia Font, Luis E. Ib\'a\~nez, Fernando Marchesano and Diego Regalado Categories: hep-th hep-ph Comments: 58 pages + appendices, 7 figures Report-no: IFT-UAM/CSIC-12-110 \\ Local SU(5) F-theory models lead naturally to Yukawa couplings for the third generation of quarks and leptons, but inducing Yukawas for the lighter generations has proven elusive. Corrections coming from gauge fluxes fail to generate the required couplings, and naively the same applies to instanton effects. We nevertheless revisit the effect of instantons in F-theory GUT constructions and find that contributions previously ignored in the literature induce the leading non-perturbative corrections to the Yukawa couplings. We apply our results to the case of 10 x 5* x 5* couplings in local SU(5) F-theory GUTs, showing that non-perturbative effects naturally lead to hierarchical Yukawas. The hypercharge flux required to break SU(5) down to the SM does not affect the holomorphic Yukawas but does modify the profile of the wavefunctions, explaining the difference between the D-quark and lepton couplings at the unification scale. The combination of non-perturbative corrections and magnetic fluxes allows to describe the measured lepton and D-quark masses of second and third generations in the SM. \\ ( http://arxiv.org/abs/1211.6529 , 1807kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6530 Date: Wed, 28 Nov 2012 07:19:45 GMT (18kb) Title: Bigravity in Kuchar's Hamiltonian formalism. 1. The General Case Authors: Vladimir O. Soloviev and Margarita V. Tchichikina Categories: hep-th Comments: 19 pages, Russian, English translation will appear MSC-class: 83D05 \\ The Hamiltonian formalism of bigravity and bimetric theories is constructed for the general form of potential between two metrics. It is natural to study the role played by the lapse and shift functions in theories with two metrics on the base of Kuchar's approach because then they do not depend on the choice of space-time coordinate frame. The algebra of first class constraints is derived in Dirac brackets constructed from the second class constraints. It is the celebrated algebra of the hypersurface deformations. Fixing one of the metrics we obtain a bimetric theory without any first class constrains. Then we can use the symmetries of the background metric to construct conserved quantities looking ultralocally when written through the potential. The special case of potential providing the less number for degrees of freedom will be treated in the companion paper. \\ ( http://arxiv.org/abs/1211.6530 , 18kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6544 Date: Wed, 28 Nov 2012 08:51:31 GMT (427kb) Title: Gauge/string duality and thermodynamic Bethe ansatz equations Authors: Yuji Satoh Categories: hep-th Comments: 22 pages, 9 figures; contribution to the proceedings of RIMS Workshop "Developments in Quantum Integrable Systems", June 14-16, 2010, Research Institute for Mathematical Sciences, Kyoto, Japan Report-no: UTHEP-653 Journal-ref: RIMS Kokyuroku Bessatsu B28 (2011) 171-192 \\ We review recent developments in the study of gluon scattering amplitudes of the four-dimensional maximally supersymmetric Yang-Mills theory at strong coupling based on the gauge/string duality and its underlying integrability. The scattering amplitudes are given by the area of minimal surfaces in five-dimensional anti-de Sitter space with a null polygonal boundary. These minimal surfaces are described by integral equations of the form of the thermodynamic Bethe ansatz equations. Generalizing the result regarding the six-point amplitudes, we observe a general connection between the minimal surfaces and the homogenous sine-Gordon model, which is a class of two-dimensional integrable models associated with certain coset conformal field theories. We also demonstrate that the identification of the underlying integrable models is useful for analyzing the amplitudes by explicitly deriving an expansion of the six-point amplitudes around a special kinematic point. \\ ( http://arxiv.org/abs/1211.6544 , 427kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6549 Date: Wed, 28 Nov 2012 09:16:14 GMT (746kb) Title: Gluon scattering amplitudes from gauge/string duality and integrability Authors: Yuji Satoh Categories: hep-th Comments: 23 pages, 7 figures; contribution to the proceedings of "Progress in Quantum Field Theory and String Theory", April 3-7, 2012, Osaka City University, Osaka, Japan Report-no: UTHEP-654 \\ We discuss gluon scattering amplitudes/null-polygonal Wilson loops of N = 4 super Yang-Mills theory at strong coupling based on the gauge/string duality and its underlying integrability. We focus on the amplitudes/Wilson loops corresponding to the minimal surfaces in AdS_3, which are described by the thermodynamic Bethe ansatz equations of the homogeneous sine-Gordon model. Using conformal perturbation theory and an interesting relation between the g-function (boundary entropy) and the T-function, we derive analytic expansions around the limit where the Wilson loops become regular-polygonal. We also compare our analytic results with those at two loops, to find that the rescaled remainder functions are close to each other for all multi-point amplitudes. \\ ( http://arxiv.org/abs/1211.6549 , 746kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6612 Date: Wed, 28 Nov 2012 14:36:39 GMT (13kb) Title: Differential forms and k-Minkowski spacetime from extended twist Authors: Tajron Juri\'c, Stjepan Meljanac and Rina \v{S}trajn Categories: hep-th Comments: 14 pages \\ We unify k-Minkowski spacetime, k-Poincar\'e algebra and differential forms.

These affect low-energy fermion and antifermion scattering processes through modifications to the nonrelativistic Yukawa potentials. The modified potentials involve novel combinations of momentum, spin, and Lorentz-violating background tensors. \\ ( http://arxiv.org/abs/1211.6614 , 13kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6670 Date: Wed, 28 Nov 2012 17:31:59 GMT (930kb) Title: Gravity, Nonlinear Gauge Fields and Charge Confinement/Deconfinement Authors: Eduardo Guendelman, Alexander Kaganovich, Emil Nissimov, Svetlana Pacheva Categories: hep-th gr-qc Comments: To appear in the proceedings of "Seventh Meeting in Modern Mathematical Physics", B.

Burrington, Amanda W. Peet, Ida G. Zadeh Categories: hep-th Comments: 30 pages, 1 figure \\ We consider general 2D orbifold CFTs of the form M^N/S_N, with M a target space manifold and S_N the symmetric group, and generalize the Lunin-Mathur covering space technique in two ways. First, we consider excitations of twist operators by modes of fields that are not twisted by that operator, and show how to account for these excitations when computing correlation functions in the covering space. Second, we consider non-twist sector operators and show how to include the effects of these insertions in the covering space. We work two examples, one using a simple bosonic CFT, and one using the D1-D5 CFT at the orbifold point. We show that the resulting correlators have the correct form for a 2D CFT. \\ ( http://arxiv.org/abs/1211.6689 , 50kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6699 Date: Wed, 28 Nov 2012 18:44:23 GMT (35kb) Title: Operator mixing for string states in the D1-D5 CFT near the orbifold point Authors: Benjamin A. Burrington, Amanda W. Peet, Ida G. Zadeh Categories: hep-th Comments: 43 pages \\ In the context of the fuzzball programme, we investigate deforming the microscopic string description of the D1-D5 system on T^4xS^1 away from the orbifold point. Using conformal perturbation theory and a generalization of Lunin-Mathur symmetric orbifold technology for computing twist-nontwist correlators developed in a companion work, we initiate a program to compute the anomalous dimensions of low-lying string states in the D1-D5 superconformal field theory. Our method entails finding four-point functions involving a string operator O of interest and the deformation operator, taking coincidence limits to identify which other operators mix with O, subtracting the identified conformal family to isolate other contributions to the four-point function, finding the mixing coefficients, and iterating. For the lowest-lying string modes, this procedure should truncate in a finite number of steps. We check our method by showing how the operator dual to the dilaton does not participate in mixing that would change its conformal dimension, as expected. Next we complete the first stage of the iteration procedure for a low-lying string state of the form \partial X \partial X \bar\partial X \bar\partial X and find its mixing coefficient. Our main qualitative result is evidence of operator mixing at first order in the deformation parameter, which means that the string state acquires an anomalous dimension. After diagonalization this will mean that anomalous dimensions of some string states in the D1-D5 SCFT must decrease away from the orbifold point while others increase. \\ ( http://arxiv.org/abs/1211.6699 , 35kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6734 Date: Wed, 28 Nov 2012 20:51:05 GMT (16kb) Title: Hyper-Entropic Gravitational Fireballs (Grireballs) with Firewalls Authors: Don N. Page Categories: hep-th gr-qc Comments: 23 pages, LaTeX \\ Recently there has been much discussion as to whether old black holes have firewalls at their surfaces that would destroy infalling observers. Though I suspect that a proper handling of nonlocality in quantum gravity may show that firewalls do not exist, it is interesting to consider an extension of the firewall idea to what seems to be the logically possible concept of hyper-entropic gravitational hot objects (gravitational fireballs or grireballs for short) that have more entropy than ordinary black holes of the same mass. Here some properties of such grireballs are discussed under various assumptions, such as assuming that their radii and entropies both go as powers of their masses as the one independent parameter, or assuming that their radii depend on both their masses and their entropies as two independent parameters. \\ ( http://arxiv.org/abs/1211.6734 , 16kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1207.7339 (*cross-listing*) Date: Tue, 31 Jul 2012 18:37:08 GMT (25kb) Title: Rank-3 root systems induce root systems of rank 4 via a new Clifford spinor construction Authors: Pierre-Philippe Dechant Categories: math-ph hep-th math.MP Comments: 7 pages. arXiv admin note: text overlap with arXiv:1205.1451 Report-no: IPPP/12/60, DCPT/12/120 MSC-class: 15A66, 51F15 \\ In this paper, we show that via a novel construction every rank-3 root system induces a root system of rank 4. In a Clifford algebra framework, an even number of successive Coxeter reflections yields - via the Cartan-Dieudonne theorem - spinors that describe rotations. In three dimensions these spinors themselves have a natural four-dimensional Euclidean structure, and discrete spinor groups can therefore be interpreted as 4D polytopes. In fact, these polytopes have to be root systems, thereby inducing Coxeter groups of rank 4. For the corresponding case in two dimensions, the groups I_2(n) are shown to be self-dual. \\ ( http://arxiv.org/abs/1207.7339 , 25kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6478 (*cross-listing*) Date: Tue, 27 Nov 2012 23:35:30 GMT (27kb) Title: A conceptual problem for non-commutative inflation and the new approach for non-relativistic inflationary equation of state Authors: U. D. Machado and R. Opher Categories: astro-ph.CO gr-qc hep-th \\ In a previous paper, we connected the phenomenological non-commutative inflation of Alexander, Brandenberger and Magueijo (2003, 2005 and 2007) with the formal representation theory of groups and algebras. In that paper, the fundamental equations of inflation followed as a consequence of a deformation of the Poincar\'e group, which induces a particular quantum representation. In this paper, we show that there exists a conceptual problem with the kind of representation that leads to the fundamental equations of the model and that the procedure to obtain those equations should be modified according to one of two possible proposals. One of them relates to the general theory of Hopf algebras. The other is based on a representation theorem of Von Neumann algebras, a proposal already suggested by us to take into account interactions in the inflationary equation of state. This reopens the problem of finding inflationary deformed dispersion relations and all developments which followed the first paper of Non-commutative Inflation. \\ ( http://arxiv.org/abs/1211.6478 , 27kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6600 (*cross-listing*) Date: Wed, 28 Nov 2012 13:29:56 GMT (23kb) Title: Traces on the Algebra of Observables of Rational Calogero Model based on the Root System Authors: S.

Simultaneously, we reproduced an older result: the algebra H_R(\nu), considered as a superalgebra with a natural parity, possesses ST(R) independent supertraces, where ST(R) is the number of conjugacy classes of elements without eigenvalue -1 belonging to W(R). \\ ( http://arxiv.org/abs/1211.6600 , 23kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6619 (*cross-listing*) Date: Wed, 28 Nov 2012 14:55:04 GMT (309kb) Title: Generation of Cosmological Flows in General Relativity (Features and Properties of Integrable Singularities) Authors: V.

As an example, we consider properties of the integrable singularities and show that they represent light horizons separating T-regions of black and white holes. Connecting an astrophysical black hole to a white hole, they lead to a natural mechanism of generating new universes. Under favorable conditions the new universes will also contain black holes which, in their turn, will give rise to another generation of universes. In this case the cosmological evolutionary tree will continue to grow to form the "hyperverse". This scenario essentially differs from other known mechanisms, such as bounce, birth from "nothing", baby-universe scenario, etc. \\ ( http://arxiv.org/abs/1211.6619 , 309kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6665 (*cross-listing*) Date: Wed, 28 Nov 2012 17:12:39 GMT (135kb) Title: Spontaneous parity violation in extreme conditions: an effective lagrangian analysis Authors: A. A. Andrianov, V. A. Andrianov, D. Espriu Categories: hep-ph hep-th nucl-th Comments: 29 pages. arXiv admin note: text overlap with arXiv:0709.0049 Report-no: ICCUB-12-472 \\ We investigate how large baryon densities (and possibly high temperatures) may induce spontaneous parity violation in the meson sector of QCD. The analysis at intermediate energy scales is done by using an extended $\sigma$-model lagrangian that includes two scalar and two pseudoscalar multiplets and fulfills low-energy QCD constraints. We elaborate on a novel mechanism of parity breaking previously proposed by the authors based on the interplay between lightest and heavier meson condensates, which therefore cannot be realized in the simplest $\sigma$ model. We emphasize that the mechanism proposed here differs from the old idea of pion condensation advocated originally by Migdal. The results are relevant for an idealized homogeneous and infinite nuclear (quark) matter where the influence of density can be examined with the help of a constant chemical potential. The model is able to describe satisfactorily the first-order phase transition to stable nuclear matter, and predicts a second-order phase transition to a state where parity is spontaneously broken. We argue that the parity breaking phenomenon is quite generic when a large enough chemical potential is present. Current quark masses are explicitly taken into account in this work and shown not to change the general conclusions. We expect that our approach will be adequate for dense nuclear matter of a few normal densities where quark percolation does not yet play a significant role. \\ ( http://arxiv.org/abs/1211.6665 , 135kb) ------------------------------------------------------------------------------ \\ arXiv:1211.6669 (*cross-listing*) Date: Wed, 28 Nov 2012 17:29:18 GMT (55kb,D) Title: Implications of Poincare symmetry for thermal field theories in finite-volume Authors: Leonardo Giusti and Harvey B. Meyer Categories: hep-lat hep-th math-ph math.MP Comments: 26 pages, 3 figures \\ The analytic continuation to an imaginary velocity $i\xi$ of the canonical partition function of a thermal system expressed in a moving frame has a natural implementation in the Euclidean path-integral formulation in terms of shifted boundary conditions. Writing the Boltzmann factor as $\exp[-L_0(H-i\xi.P)]$, the Poincare invariance underlying a relativistic theory implies a dependence of the free-energy on $L_0$ and the shift $\xi$ only through the combination $\beta= L_0 \sqrt{1+\xi^2}$. This in turn implies a set of Ward identities, some of which were previously derived by us, among the correlators of the energy-momentum tensor. In the infinite-volume limit they lead to relations among the cumulants of the total energy distribution and those of the momentum, i.e. they connect the energy and the momentum distributions in the canonical ensemble. In finite volume the Poincare symmetry translates into exact relations among partition functions and correlation functions defined with different sets of (generalized) periodic boundary conditions. They have interesting applications in lattice field theory. In particular, they offer Ward identities to renormalize non-perturbatively the energy-momentum tensor and novel ways to compute thermodynamic potentials. At fixed bare parameters they also provide a simple method to vary the temperature in much smaller steps than with the standard procedure. \\ ( http://arxiv.org/abs/1211.6669 , 55kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1109.6566 replaced with revised version Wed, 28 Nov 2012 07:36:22 GMT (580kb,D) Title: The Inflationary Wavefunction and its Initial Conditions Authors: Daniel Carney, Willy Fischler, Sonia Paban and Navin Sivanandam Categories: hep-th astro-ph.CO Comments: 17 pages, 1 figure, numerical example and analysis thereof added in this version Report-no: UTTG-14-11 \\ ( http://arxiv.org/abs/1109.6566 , 580kb) ------------------------------------------------------------------------------ \\ arXiv:1111.2305 (*cross-listing*) replaced with revised version Wed, 28 Nov 2012 14:51:38 GMT (318kb) Title: New Q-ball Solutions in Gauge-Mediation, Affleck-Dine Baryogenesis and Gravitino Dark Matter Authors: Francesca Doddato, John McDonald Categories: hep-ph astro-ph.CO hep-th Comments: 13 pages, 9 figures.
