A Nonlocal Schwinger Model
Ludovic Fraser-Taliente, Christopher P. Herzog, Abhay Shrestha
We solve a system of massless fermions constrained to two space-time dimensions interacting via a space-time dimensional Maxwell field. Through dimensional reduction to the def…

Conformal Surface Defects in Maxwell Theory are Trivial
Christopher P. Herzog, Abhay Shrestha
We consider a free Maxwell field in four dimensions in the presence of a codimension two defect. Reflection positive, codimension two defects which preserve conformal symmetry in t…

Two Point Functions in Defect CFTs
Christopher P. Herzog, Abhay Shrestha
This paper is designed to be a practical tool for constructing and investigating two-point correlation functions in defect conformal field theory, directly in physical space, betwe…
