Findings

Black hole temperature depends on mass.

Thermodynamic limit breaks down before complete evaporation.

Higher-loop quantum effects are necessary for full description.

Abstract

Black hole spacetimes can arise when a Liouville field is coupled to two- dimensional gravity. Exact solutions are obtained both classically and when quantum corrections due to back reaction effects are included. The black hole temperature depends upon the mass and the thermodynamic limit breaks down before evaporation of the black hole is complete, indicating that higher-loop effects must be included for a full description of the process.
