Description
We construct black hole solutions in four-dimensional Einstein-Yang-Mills theory with U(2) gauge group. We take a near-extremal limit of the black hole solutions coupled with Yang-Mills instantons which reduces to Witten's multi-instanton solutions described by the Liouville theory in two-dimensional Abelian Higgs model.
We consider a semi-classical quantization of the near-extremal black holes coupled with the Witten instantons in a zero-temperature limit and clarify how zero-modes in gravity and Yang-Mills theory play a crucial role in black hole thermodynamics.
