The gravitational S-matrix from the path integral: asymptotic symmetries and soft theorems
Jack Isen, Per Kraus, Ruben Monten +1
We extend a previously developed formulation of the S-matrix, based on a path integral with asymptotic boundary conditions, to include gravity. The path integral defines a Carrolli…
Carrollian Partition Function for Bulk Yang-Mills Theory
Per Kraus, Richard M. Myers
The path integral over massless quantum fields in Minkowski space with scattering boundary conditions defines a Carrollian partition function on the null boundary. We develop this…
Locality and Conserved Charges in -Deformed CFTs
Ruben Monten, Richard M. Myers, Konstantinos Roumpedakis
We investigate the locality properties of -deformed CFTs within perturbation theory. Up to third order in the deformation parameter, we find a Hamiltonian operator w…
Carrollian Partition Functions and the Flat Limit of AdS
Per Kraus, Richard M. Myers
The formulation of the S-matrix as a path integral with specified asymptotic boundary conditions naturally leads to the realization of a Carrollian partition function defined on th…
S-Matrix Path Integral Approach to Symmetries and Soft Theorems
Seolhwa Kim, Per Kraus, Ruben Monten +1
We explore a formulation of the S-matrix in terms of the path integral with specified asymptotic data, as originally proposed by Arefeva, Faddeev, and Slavnov. In the tree approxim…
Systematics of Boundary Actions in Gauge Theory and Gravity
Seolhwa Kim, Per Kraus, Richard M. Myers
We undertake a general study of the boundary (or edge) modes that arise in gauge and gravitational theories defined on a space with boundary, either asymptotic or at finite distanc…
Field Theory of Interacting Boundary Gravitons
Stephen Ebert, Eliot Hijano, Per Kraus +2
Pure three-dimensional gravity is a renormalizable theory with two free parameters labelled by and . As a consequence, correlation functions of the boundary stress tensor in…
3D Gravity in a Box
Per Kraus, Ruben Monten, Richard M. Myers
The quantization of pure 3D gravity with Dirichlet boundary conditions on a finite boundary is of interest both as a model of quantum gravity in which one can compute quantities wh…
