Small Black Holes and Superconformal Quantum Mechanics
Joris Raeymaekers
TL;DR
This paper extends the holographic description of black hole microstates to small black holes with zero horizon area, using superconformal quantum mechanics on D0-branes, building on prior proposals for N=2 black holes.
Contribution
It demonstrates that the superconformal quantum mechanics framework applies successfully to small black holes, broadening the scope of holographic microstate descriptions.
Findings
Successfully applied superconformal quantum mechanics to small black holes
Extended holographic microstate description to black holes with vanishing horizon
Connected microstates to Dabholkar-Harvey states
Abstract
Recently, Gaiotto, Strominger and Yin have proposed a holographic representation of the microstates of certain N=2 black holes as chiral primaries of a superconformal quantum mechanics living on D0-branes in the attractor geometry. We show that their proposal can be succesfully applied to `small' black holes which are dual to Dabholkar-Harvey states and have vanishing horizon area in the leading supergravity approximation. This note is a summary of hep-th/0505176 with S. Kim.
