In order to disentangle superradiance from finite-temperature effects, we consider an extremal, rotating D1-D5-P black hole that has an ergosphere and is not supersymmetric. We explain how the microscopic dual accounts for the superradiant ergosphere of this black hole. The bound 0< omega < m Omega_H on superradiant mode frequencies is argued to be a consequence of Fermi-Dirac statistics for the spin-carrying degrees of freedom in the dual CFT. We also compute the superradiant emission rates from both sides of the correspondence, and show their agreement.19 p.application/pdfeng(c) The American Physical Society, 2008Teoria quànticaForats negres (Astronomia)Quantum theoryBlack holes (Astronomy)info:eu-repo/semantics/article559785info:eu-repo/semantics/openAccess
