ABSTRACT: In the microcanonical ensemble, sufficiently small black holes in AdS5 x S⁵ are affected by the Gregory-Laflamme instability. This results in new families of black holes that break the symmetries of the S⁵, including lumpy black holes, black belts, and localised black holes. By the AdS/CFT correspondence, this effect is dual to spontaneously breaking the R-symmetry of N=4 super Yang-Mills. I will describe these new black hole solutions, their numerical construction, their phase diagram, and the resulting expectation value of scalar operators in the dual field theory.
