Talk Title: "Checkerboard black branes and inhomogeneity in AdS/CFT"


I will present asymptotically AdS black brane solutions for which all continuous spatial symmetries of the brane are spontaneously broken. Through holography these solutions describe ordered phases of a CFT whose charge and current densities exhibit a checkerboard pattern. I will also discuss the situation where these symmetries are explicitly broken by deformations of the CFT, emphasising physical and technical differences. Some black holes of this latter type can be constructed analytically and are shown to capture the key physical property of finite DC conductivity in the dual field theory.
