Black hole spectroscopy and AdS2 holography
Abstract We compute the spectrum of extremal nonBPS black holes in four dimensions by studying supergravity on their AdS2 × S 2 near horizon geometry. We find that the spectrum exhibits significant simplifications even though supersymmetry is completely broken. We interpret our results in the framew...

| Summary: | Abstract We compute the spectrum of extremal nonBPS black holes in four dimensions by studying supergravity on their AdS2 × S 2 near horizon geometry. We find that the spectrum exhibits significant simplifications even though supersymmetry is completely broken. We interpret our results in the framework of nAdS2/nCFT1 correspondence and by comparing with dimensional reduction from AdS3/CFT2 duality. As an additional test we compute quantum corrections to extremal black hole entropy on the nonBPS branch and recover results previously determined using very different methods. |
