The AdS^2_{\theta}/CFT_1 Correspondence and Noncommutative Geometry II: Noncommutative Quantum Black Holes
Abstract
In this article we present the construction of noncommutative AdS^2_{\theta} black hole and its four-dimensional Yang-Mills IKKT-type matrix model which includes two competing Myers term one responsible for the condensation of pure AdS^2_{\theta} and the other one responsible for the condensation of the dilaton field. It is argued that the phase diagram of this matrix model features three phases: 1) A gravitational phase (AdS^2_{\theta} black hole), 2) A geometric phase (AdS^2_{\theta} background) and 3) A Yang-Mills phase. The Hawking process is therefore seen as an exotic line of discontinuous transitions between the gravitational and geometrical phases. Alternatively, a noncommutative non-linear sigma model describing the transition of the dilaton field between the gravitational and geometrical phases is also constructed.

This is the second part of a three-parts study in which we attempt a synthesis between the principles of noncommutative geometry and the principles of the gauge/gravity correspondence. Part I:arXiv:2108.13982, Part III:arXiv:2109.01010 [hep-th]
