Uplifting dyonic AdS4 black holes on seven-dimensional Sasaki-Einstein manifolds
Abstract
We revisit non-rotating, dyonically charged, and supersymmetric AdS4 black holes, which are solutions of N=2 gauged supergravity with vector- and hyper-multplets. Uplifting the near horizon solutions to D=11 supergravity on seven-dimensional Sasaki-Einstein manifolds, we show that dyonic AdS4 black holes correspond to AdS2 solutions with electric and magnetic baryonic fluxes in D=11 supergravity. We identify the off-shell AdS4 black hole solutions with parameters of D=11 AdS2 solutions without imposing the equations of motion. We calculate the entropy of dyonic black holes, carefully analyzing the Page charge quantization conditions.
