Abstract:Within the gauge/gravity correspondence, black holes are dual to CFT thermal states.
I will discuss asymptotically global AdS5 x S5 black holes that are localised on the S5. These are solutions to type IIB supergravity with S8 horizon topology that dominate the theory in the microcanonical ensemble at small energies. At higher energies, there is a first-order phase transition to AdS5-SchwarzschildxS5. By the AdS/CFT correspondence, this transition is dual to spontaneously breaking the SO(6) R-symmetry of N = 4 super Yang-Mills down to SO(5).
I will also discuss localised and nonuniform thermal states of super-Yang-Mills on a circle at strong coupling and associated phase transitions that might be soon reproduced by lattice computations.
