Exploring Defects with Degrees of Freedom in Free Scalar CFTs - Dr. Jacopo Sisti (Uppsala University)

Seminario di fisica teorica
Abstract:
Defects in conformal field theories are interesting objects to study that offer rich insights from both formal and applied perspectives. In this talk, I will begin with an introduction to defect CFTs and defect Weyl anomalies. Then, I will discuss how to construct conformal defects in free scalar field CFTs in diverse dimensions, considering both quadratic cases and those involving defect interactions. The latter can be realized by coupling the bulk free scalar to lower dimensional theories, including the unitary family of minimal models M(p, p+ 1). Additionally, I will consider monodromy defects associated with a global U(1) flavour symmetry, where one can study both self-defect interactions and couplings to Minimal <a href="http://Models.
