Description
Critical systems with a boundary are important for various phenomenological, theoretical and even experimental applications. In this case, the formalism of Boundary CFT and the Conformal Bootstrap has led to a firm theoretical framework to study this scenario.
Less explored is the case of systems with two intersecting boundaries, which form a co-dimension 2 edge. I will review some old results by Cardy in the framework of the epsilon expansion, and present a recent Bootstrap formulation of this setup which defines this class of systems non-perturbatively.
I will finish by pointing out some open problems that can potentially be addressed in the Bootstrap framework.
