BID - Quantum field theory with boundaries, impurities, and defects

Critical phenomena in the presence of interfaces provide a much richer arena than their more studied cousin of boundary critical phenomena. In this talk, I’ll review certain observables that are new and unique in interface conformal field theory and then demonstrate some novel bounds we can derive on these quantities using techniques from holography and quantum information. This work is based on collaboration with Yuya Kusuki, Hiroshi Ooguri, Haoyu Sun, and Mianqi Wang.
