Entanglement entropy of gravitational edge modes

Journal of High Energy Physics, 2022
We consider the linearised graviton in 4d Minkowski space and decompose it into tensor spherical harmonics and fix the gauge. The Gauss law of gravity implies that certain radial components of the Riemann tensor of the graviton on the sphere labels the ...

Explicit expressions for Virasoro singular vectors

Journal of High Energy Physics
We present two explicit expressions for generic singular vectors of type (r, s) of the Virasoro algebra. These results follow from the paper of Bauer et al. which presented recursive methods to construct the vectors.

Gapped dilatons in scale invariant superfluids [PDF]

, 2020
We study a paradigmatic model in field theory where a global U(1) and scale symmetries are jointly and spontaneously broken. At zero density the model has a noncompact flat direction, which at finite density needs to be slightly lifted. The resulting low-

Spinors, embeddings and gravity

, 1988
This thesis is concerned with the theory of spinors, embeddings and everywhere invariance with applications to general relativity. The approach is entirely geometric with particular emphasis on the use of natural structures.

Symmetries and couplings of non-relativistic electrodynamics [PDF]

, 2016
We examine three versions of non-relativistic electrodynamics, known as the electric and magnetic limit theories of Maxwell's equations and Galilean electrodynamics (GED) which is the off-shell non-relativistic limit of Maxwell plus a free scalar field ...

Quasi-characters for three-character rational conformal field theories

Journal of High Energy Physics
We revisit (3, 0) and (3, 3) admissible solutions obtained using the MLDE method. We show that all (3, 0) solutions can be written in terms of a universal formula involving the 3 F 2 hypergeometric function that takes into account the monodromy at the ...

QCD in AdS

Journal of High Energy Physics
We study QCD on AdS space with scalars or fermions in the fundamental representation, extending earlier results on pure Yang-Mills theory. In the latter, the Dirichlet boundary condition is conjectured to disappear via merger and annihilation, as ...

Weyl and Conformal Symmetries

, 2019
The problem whether scale invariance implies full conformal invariance, for special relativistic classical field theories, was resolved in the literature by exploiting the Weyl and diffeomorphic symmetries held simultaneously by the suitably improved ...

Large charge, semiclassics and superfluids : from broken symmetries to conformal field theories

, 2020
This thesis explores the application of semiclassical methods in the study of states with large quantum numbers for theories invariant under internal symmetries. In the first part of the thesis, we study zero-temperature superfluids.

Asymptotic symmetries of AdS2 Branes

, 2019
11 pages, Latex file. Minor changes and some extra referencesI analyze the asymptotic symmetries of a theory of gravity in a background consisting of two patches of ${\rm AdS}_3$ spacetime glued together along an ${\rm AdS}_2$ brane.
