To go or not to go with the flow: Hawking radiation at strong coupling

Abstract

We construct the gravitational dual of a one-parameter class of states of strongly coupled SU(N)SU(N) N=4\mathcal{N}=4 SYM at infinite NN and asymptotic temperature TT_{\infty}, on a fixed Schwarzschild black hole background with temperature TBHT_{\mathrm{BH}}. The resulting bulk geometry is of the flowing type and allow us to measure Hawking radiation at strong coupling. The outgoing Hawking flux is a function of the dimensionless ratio τT/TBH\tau\equiv T_{\infty}/T_{\mathrm{BH}} and appears to be non-monotonic in τ\tau. At present, we have no field theory understanding for this behaviour.
