Abstract
There has recently been considerable interest in describing the universality classes that can live on impurities within an otherwise conformal system. A number of these defects, such as the magnetic line defect in the O(N) model, have been studied extensively, but a more complete list of such theories is lacking. In this talk I will detail a series of recent works advancing a partial classification of lines, surfaces and interfaces appearing in scalar, and scalar-fermion bulks in d=4-ε. I will then discuss various generalizations of these defects, such as composite defects as well as defects lying within an RG interface between bulk universality classes.
Series This talk is part of the Isaac Newton Institute Seminar Series series.
