Abstract
I will discuss recent work on N=4 super-Yang-Mills theory with Gaiotto-Witten boundary conditions. This broad class of theories with rich boundary dynamics comprises the most supersymmetric boundary conformal field theories in four dimensions, and in the context of string theory it allows for a proper realization of double holography. We will discuss their holographic description, a tight interplay between the holographic duals and the matrix models arising from supersymmetric localization, defect one-point functions, and large-charge operators.
