摘要：

We compute the spectrum of extremal nonBPS black holes in four dimensions by studying supergravity on their AdS(2) x 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 nAdS(2)/nCFT(1) correspondence and by comparing with dimensional reduction from AdS(3)/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.
