Confinement Versus Screening in the Schwinger Model on AdS from Bosonization and Tensor Networks
Sriram Bharadwaj, Jack Isen, Zhong-Bo Kang
We analyze confinement and screening in single-flavor quantum electrodynamics (QED) on two-dimensional anti-de Sitter space (AdS), with and without a Schwarzschild black ho…

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…
