Conformal boundary conditions for free fields
byEdoardo Lauria
Abstract:I will discuss the problem of classifying (interacting) conformal boundary conditions for the simplest bulk conformal field theories: free fields. I will mention concrete examples based on perturbation theory, and then describe results using the numerical conformal bootstrap approach, specifically in the case of a scalar field in four and three bulk dimensions.

Critical phenomena, boundary conformal field theory, conformal bootstrap.
