Description
I'll discuss recent results on the dynamics of defects in conformal field theory. In particular, I'll describe the phenomena of defect fusion and the factorization of spacetime under renormalization group flows on defects. I'll illustrate these phenomena with the so-called pinning field defects which have simple definitions in quantum field theory and also comment on the broader implications for understanding extended operators.
