IAS CMP/QFT Group Meeting
Generalized Pinning Fields and Renormalization Group Flows
Abstract: It is commonly believed that exact infra-red (IR) solutions for renormalization group (RG) flows are rare to come by. In this talk, we will consider codimension-one RG flows from pinning fields coupled to bulk local operators in conformal field theories (CFTs). Using tools from functional analysis, together with symmetry and anomaly matching, we find exact fixed point solutions for a vast zoo of such flows in d=2,3, chart the resulting landscape of conformal defects in garden-variety CFTs and uncover exotic new classes of surface critical behavior.
