Description
In this talk we discuss recent developments in Defect Conformal Field Theory (DCFT). Focusing on specific examples in gauge theories, we study how the insertion of a Wilson line (representing an infinitely massive charged source) introduces relevant operators that can trigger a renormalisation group flow on the defect. In particular, we examine how quartic (four-fermion) deformations on the line change the fixed point structure of the theory.
