Exact microstate counting for dyonic black holes in AdS4

Exact microstate counting for dyonic black holes in AdS4

We present a counting of microstates of a class of dyonic BPS black holes in AdS4 which precisely reproduces their Bekenstein–Hawking entropy. The counting is performed in the dual boundary description, that provides a non-perturbative definition of quantum gravity, in terms of a twisted and mass-de...
