Physics Theory Seminar with Avia Raviv-Moshe on ine Defects in CFTs: from Impurities to Wilson Lines

Avia Raviv-Moshe (hosted by Zohar Nussinov) from the Simons Center for Geometry and Physics will be presenting the seminar on "ine Defects in CFTs: from Impurities to Wilson Lines"

Line defects (one-dimensional defects) in CFTs provide a framework that is of relevance to describe various physical systems, with applications ranging from condensed matter physics to conformal gauge theories. I will review some general properties of line defects in CFTs, especially in the context of RG flows on line defects, where recent progress has been achieved. Then, we will focus on three types of applications: external field defects, models of spin impurities, and Wilson lines in conformal gauge theories.

This lecture was made possible by the William C. Ferguson fund.
