CLOWN S & BLACK HOLES Ram Brustein, Merav Hadad Phys. Lett. B718 (2012) / The canonical conjugate to black hole entropy in general theories of gravity

Motivation Black hole entropy counts the degrees of freedom of something unclear Investigate common characteristics of general theories of gravity Building blocks of quantum gravity. 212/

Entropy of black holes in general theories of gravity Wald entropy: 312/

Black hole: radial direction Time - second normal direction. Integration over the surface area of the horizon 412/ Brown :gr-qc/ gr-qc/ Identifying the canonical conjugate of Wald entropy from the action

Geometric meaning : The opening angle at - plane 512/

Quantum picture In the classical limit (specific heat ) Non zero uncertainty at the opening angle 612/

Physical meaning Quantum black hole is expected to be superposition of metrics with conical singularities. 712/

Example of quantum gravity - Strings String theory identifies the “microstates “ of a (extremal) black hole as modes of different vibrations of the strings. (hep-th/ ) These vibrations create metrics with conical singularities at the horizon with (N integer ). (hep-th/ ) In string theory the “microstates“ of the black hole are metrics with (quantized) conical singularities at the horizon. 812/

Summary In any theory of gravity the entropy of a black hole is canonical to the opening angle in Prediction - a quantum black hole is a superposition of metrics with conical singularities. The prediction fits quantum gravity of string theory. 912/
