On March 1 we will have a seminar by
Gabriel Cuomo (SCGP)
Title: Line defects in CFTs: renormalization group flows and semiclassical limits
Abstract:
I will discuss line defects in d-dimensional Conformal Field Theories (CFTs). I will first review recent general results on the monotonicity of defect RG flows for line defects. I will then discuss three physically interesting examples of line defects: magnetic field defects, spin impurities, and Wilson lines. In particular, I will present a recently developed semiclassical approach, which allows studying spin impurities and Wilson lines in large representations.
