It is argued that the general four-dimensional extremal Kerr-Newman-AdS-dS black hole is holographically dual to a (chiral half of a) two-dimensional CFT, generalizing an argument given recently for the special case of extremal Kerr. Specifically, the asymptotic symmetries of the near-horizon region of the general extremal black hole are shown to be generated by a Virasoro algebra. Semiclassical formulae are derived for the central charge and temperature of the dual CFT as functions of the… 

Extremal Black Hole/CFT Correspondence in (Guaged) Supergravities

We extend the investigation of the recently proposed Kerr/conformal field theory correspondence to large classes of rotating black hole solutions in gauged and ungauged supergravities. The

The Kerr/CFT correspondence and its extensions

The main results of the Kerr/CFT correspondence and its extensions are presented using only tools from gravity and quantum field theory and the entropy of extremal spinning or charged black holes is shown to match with a chiral half of Cardy's formula.

CFT duals of Kerr-Taub-NUT and beyond

The duality relating the four-dimensional Kerr-Taub-NUT black hole to a thermal two-dimensional CFT with central charges cL = cR = 12J0 is analyzed in detail, generalizing an argument given recently

General hidden conformal symmetry of 4D Kerr-Newman and 5D Kerr black holes

There are two known CFT duals, namely the J-picture and the Q-picture, for a four-dimensional Kerr-Newman black hole, corresponding to the angular momentum J and the electric charge Q respectively.

CFT duals on extremal rotating NUT black holes

We investigate the Kerr–Newman–NUT black hole solution obtained from Plebański–Demiański solutions with several assumptions. The origin of the microscopic entropy of this black hole is investigated

What is a chiral 2d CFT? And what does it have to do with extremal black holes?

The near horizon limit of the extremal BTZ black hole is a “self-dual orbifold” of AdS3. This geometry has a null circle on its boundary, and thus the dual field theory is a Discrete Light Cone

ON THE CFT DUALS FOR NEAR-EXTREMAL BLACK HOLES

We consider Kerr–Newman–AdS–dS black holes near extremality and work out the near-horizon geometry of these near-extremal black holes. We identify the exact U(1)L×U(1)R isometries of the near-horizon

Dual CFT on Dyonic Kerr-Sen black hole, its gauged and ultraspinning counterparts

We demonstrate that rotating dyonic black holes in Einstein-Maxwell-Dilaton-Axion (EMDA) theory is holographically dual with 2D conformal field theory. We first investigate the duality on dyonic

The Kerr/CFT Correspondence and its Extensions

We present a first-principles derivation of the main results of the Kerr/CFT correspondence and its extensions using only tools from gravity and quantum field theory, filling a few gaps in the

What is a chiral 2 d CFT ? And what does it have to do with extremal black holes ?

The near horizon limit of the extremal BTZ black hole is a “self-dual orbifold” of AdS3. This geometry has a null circle on its boundary, and thus the dual field theory is a Discrete Light Cone
