Open AccessTopological gauging and double current deformations
We study solvable deformations of two-dimensional quantum field theories driven by a bilinear operator constructed from a pair of conserved U(1) currents Ja. We propose a quantum formulation of these deformations...

Open AccessSupertranslation-invariant dressed Lorentz charges
We present an explicit formula for Lorentz boosts and rotations that commute with BMS supertranslations in asymptotically flat spacetimes. Key to the construction is the use of infrared regularizations and of ...

Open AccessComponent actions of liberated \( \mathcal{N} \) = 1 supergravity and new Fayet-Iliopoulos terms in superconformal tensor calculus
We explicitly compute the component action of certain recently discovered new N $$ \mathca...

Open AccessPartition functions of Chern-Simons theory on handlebodies by radial quantization
We use radial quantization to compute Chern-Simons partition functions on handlebodies of arbitrary genus. The partition function is given by a particular transition amplitude between two states which are defi...

Open AccessCylinder transition amplitudes in pure AdS3 gravity
A spacelike surface with cylinder topology can be described by various sets of canonical variables within pure AdS3 gravity. Each is made of one real coordinate and one real momentum. The Hamiltonian can be eithe...

Open AccessKac-Moody and Virasoro characters from the perturbative Chern-Simons path integral
We evaluate to one loop the functional integral that computes the partition functions of Chern-Simons theories based on compact groups, using the background field method and a covariant gauge fixing. We compar...

Open AccessComments on Lorentz transformations, dressed asymptotic states and Hawking radiation
We consider two applications of the factorization of infrared dynamics in QED and gravity. The first is a redefinition of the Lorentz transformations that makes them commute with supertranslations. The other i...

Open AccessNotes on relevant, irrelevant, marginal and extremal double trace perturbations
Double trace deformations, that is products of two local operators, define perturbations of conformal field theories that can be studied exactly in the large-N limit. Even when the double trace deformation is irr...

Open AccessOn a canonical quantization of 3D Anti de Sitter pure gravity
We perform a canonical quantization of pure gravity on AdS 3 using as a technical tool its equivalence at the classical level with a Chern-Simons theory with gauge group ...

Open Accessℛ2 supergravity
We formulate R2 pure supergravity as a scale invariant theory built only in terms of superfields describing the geometry of curved superspace. The standard supergravity duals are obtained in both “old” and “new” ...

Open AccessOn the central charge of spacetime current algebras and correlators in string theory on AdS 3
Spacetime Virasoro and affine Lie algebras for strings propagating in AdS 3 are known to all orders in α′. The central extension of such algebras is a string vertex, whose expectation value can de...

Open AccessFree boundary conditions and the AdS3/CFT2 correspondence
We show that recently proposed free boundary conditions for AdS3 are dual to two-dimensional quantum gravity in certain fixed gauges. In particular, we note that an appropriate identification of the generator of ...

Nonlinear dynamics of parity-even tricritical gravity in three and four dimensions
Recently proposed “multicritical” higher-derivative gravities in Anti de Sitter space carry logarithmic representations of the Anti de Sitter isometry group. While generically non-unitary already at the quadra...

New sum rules from low energy Compton scattering on arbitrary spin target
We derive two sum rules by studying the low energy Compton scattering on a target of arbitrary (nonzero) spin j. In the first sum rule, we consider the possibility that the intermediate state in the scattering ca...

Open AccessUnitary truncations and critical gravity: a toy model
We investigate a higher-derivative scalar field model in a fixed d + 1 dimensional AdS background as a toy model for a gravitational dual to a higher-rank logarithmic CFT. The holographic two-point correlation fu...

Flux discharge cascades in various dimensions
We study the dynamics of electric flux discharge by charged particle pair or spherical string or membrane production in various dimensions. When electric flux wraps at least one compact cycle, we find that a s...
