Codimension one defects in free scalar field theory
Seolhwa Kim, Per Kraus, Zhengdi Sun
We study various aspects of codimension one defects in free scalar field theory, with particular emphasis on line defects in two-dimensions. These defects are generically non-confo…

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…
