The Kerr/CFT Correspondence and String Theory

Understand

The Kerr/CFT correspondence is a holographic duality between a two dimensional chiral conformal field theory (CFT) and the very near horizon limit of an extremal black hole, which includes an AdS2 structure.

• To understand the dual chiral CFT2, we apply the Kerr/CFT correspondence to a certain class of black holes embedded in string theory, which include the D1-D5-P and the BMPV black holes, and obtain the correct entropies for the black holes microscopically.
• These have an AdS3 structure in the near horizon geometry and an AdS2 structure in the very near horizon geometry.
• We identified one of the two Virasoro symmetries in the nonchiral CFT2 dual to the AdS3, i.e.
