Gravitational Actions in Two Dimensions and the Mabuchi Functional
Frank Ferrari, Semyon Klevtsov, Steve Zelditch
The Mabuchi energy is an interesting geometric functional on the space of Kähler metrics that plays a crucial rôle in the study of the geometry of Kähler manifolds. We show that th…
Simple matrix models for random Bergman metrics
Frank Ferrari, Semyon Klevtsov, Steve Zelditch
Recently, the authors have proposed a new approach to the theory of random metrics, making an explicit link between probability measures on the space of metrics on a Kahler manifol…
Helicity-1/2 Mode as a Probe of Interactions of Massive Rarita-Schwinger Field
Rakibur Rahman
We consider the electromagnetic and gravitational interactions of a massive Rarita-Schwinger field. Stueckelberg analysis of the system, when coupled to electromagnetism in flat sp…
Tensor hierarchies, Borcherds algebras and E11
Jakob Palmkvist
Gauge deformations of maximal supergravity in D=11-n dimensions generically give rise to a tensor hierarchy of p-form fields that transform in specific representations of the globa…
Real forms of extended Kac-Moody symmetries and higher spin gauge theories
Marc Henneaux, Axel Kleinschmidt, Hermann Nicolai
We consider the relation between higher spin gauge fields and real Kac-Moody Lie algebras. These algebras are obtained by double and triple extensions of real forms g_0 of the fini…
SUSY Enhancements in (0,4) Deformations of AdS_3/CFT_2
Stéphane Detournay, Joshua M. Lapan, Mauricio Romo
We discuss a marginal deformation of the SL(2,R) x SU(2) x U(1)^4 WZW model, which describes string theory on AdS_3 x S^3 x T^4, that corresponds to warping the S^3 factor. This de…
Asymptotically warped anti-de Sitter spacetimes in topologically massive gravity
Marc Henneaux, Cristian Martinez, Ricardo Troncoso
Asymptotically warped AdS spacetimes in topologically massive gravity with negative cosmological constant are considered in the case of spacelike stretched warping, where black hol…
Extended Charged Events and Chern-Simons Couplings
Claudio Bunster, Andrés Gomberoff, Marc Henneaux
Recently, the concept of dynamical extended charged events has been introduced, and it has been argued that they should play as central a role as that played by particles or ordina…
Inverse Scattering Construction of a Dipole Black Ring
Jorge V. Rocha, Maria J. Rodriguez, Amitabh Virmani
Using the inverse scattering method in six dimensions we construct the dipole black ring of five dimensional Einstein-Maxwell-dilaton theory with dilaton coupling a = 2(2/3)^(1/2).…
Random Geometry, Quantum Gravity and the Kähler Potential
Frank Ferrari, Semyon Klevtsov, Steve Zelditch
We propose a new method to define theories of random geometries, using an explicit and simple map between metrics and large hermitian matrices. We outline some of the many possible…
Negative Refraction and Superconductivity
Antonio Amariti, Davide Forcella, Alberto Mariotti +1
We discuss exotic properties of charged hydrodynamical systems, in the broken superconducting phase, probed by electromagnetic waves. Motivated by general arguments from hydrodynam…
Negative Refractive Index in Hydrodynamical Systems
Antonio Amariti, Davide Forcella, Alberto Mariotti
We discuss the presence of exotic electromagnetic phenomena in systems with finite charge density which are described by hydrodynamics. We show that such systems generically have n…
Random Kähler Metrics
Frank Ferrari, Semyon Klevtsov, Steve Zelditch
The purpose of this article is to propose a new method to define and calculate path integrals over metrics on a Kähler manifold. The main idea is to use finite dimensional spaces o…
Asymptotic Flatness, Taub-NUT, and Variational Principle
Amitabh Virmani
Using hyperbolic temporal and spatial cut-offs to define 4d asymptotically flat spacetimes, we show that supertranslation ambiguities in the asymptotic fields can all be removed ev…
Relaxing the Parity Conditions of Asymptotically Flat Gravity
Geoffrey Compère, François Dehouck
Four-dimensional asymptotically flat spacetimes at spatial infinity are defined from first principles without imposing parity conditions or restrictions on the Weyl tensor. The Ein…
On Lorentz-Violating Supersymmetric Quantum Field Theories
Diego Redigolo
We study the possibility of constructing Lorentz-violating supersymmetric quantum field theories under the assumption that these theories have to be described by lagrangians which…
BMS charge algebra
Glenn Barnich, Cedric Troessaert
The surface charges associated with the symmetries of asymptotically flat four dimensional spacetimes at null infinity are constructed. They realize the symmetry algebra in general…
On the symmetry orbits of black holes in non-linear sigma models
Josef Lindman Hörnlund
Breitenlohner, Maison and Gibbons claimed some time ago that all bona-fide four dimensional asymptotically flat non-degenerate black holes are in a symmetry orbit of the Schwarzsch…
Arrows of Time in the Bouncing Universes of the No-boundary Quantum State
James Hartle, Thomas Hertog
We derive the arrows of time of our universe that follow from the no-boundary theory of its quantum state (NBWF) in a minisuperspace model. Arrows of time are viewed four-dimension…
Unifying N=5 and N=6
Jakob Palmkvist
We write the Lagrangian of the general N=5 three-dimensional superconformal Chern-Simons theory, based on a basic Lie superalgebra, in terms of our recently introduced N=5 three-al…
The Action for Twisted Self-Duality
Claudio Bunster, Marc Henneaux
One may write the Maxwell equations in terms of two gauge potentials, one electric and one magnetic, by demanding that their field strengths should be dual to each other. This requ…
Non-supersymmetric CS-matter theories with known AdS duals
Davide Forcella, Alberto Zaffaroni
We consider three dimensional conformal field theories living on a stack of N anti-M2 branes at the tip of eight-dimensional supersymmetric cones. The corresponding supergravity so…
Pseudo-Goldstini in Field Theory
Riccardo Argurio, Zohar Komargodski, Alberto Mariotti
We consider two SUSY-breaking hidden sectors which decouple when their respective couplings to the visible particles are switched off. In such a scenario one expects to find two li…
Holography For a De Sitter-Esque Geometry
Dionysios Anninos, Sophie de Buyl, Stephane Detournay
Warped dS arises as a solution to topologically massive gravity (TMG) with positive cosmological constant and Chern-Simons coefficient in the region $μ^2 \ell…
