Supersymmetric black holes in \(AdS_4\) and their CFT duals
The microscopic description of the 4 dimensional supersymmetric (or BPS) black holes in flat space has already been well understood via the AdS/CFT correspondence on the black hole horizon. In this talk I address the similar problem of finding the dual description for BPS black holes in \(AdS_4\). The gravity picture of a flow between asymptotic \(AdS_4\) and \(AdS_2 \times S^2\) on the horizon can be understood as a renormalization group (RG) flow between a 3d and a 1d superconformal field theory. I discuss in some detail both the supergravity and the field theory side, providing evidence for their precise match. At the end I present a proposal for the 1d CFT states that make up the black hole entropy.
