I will explain how a local operator in two-dimensional conformal field theory can be factorized into a holomorphic and an anti-holomorphic defect operator connected through a topological defect line, and discuss implications on Lorentzian dynamics in the conformal Regge limit including aspects of chaos.I will derive a formula for the infinite boost limit, which holographically encodes the transparency/opacity of bulk scattering, in terms of the action of topological defect lines on local operators, and argue for a unitarity bound on the opacity. Factorization also gives a formula relating the local and defect operator algebras and fusion categorical data. I will review factorization in rational conformal field theory from a defect perspective, and examine irrational theories. |
