On the Entropy of Quantum Fields in Black Hole Backgrounds
S. P. de Alwis, N. Ohta
We show that the partition function for a scalar field in a static spacetime background can be expressed as a functional integral in the corresponding optical space, and point out…

Lessons of Quantum 2D Dilaton Gravity
S. P. de Alwis, D. A. MacIntire
Based on the analysis of two dimensional dilaton gravity we argue that the semiclassical equations of black hole formation and evaporation should not be interpreted in terms of exp…

The Problem of Time and Quantum Black Holes
S. P. de Alwis, D. A. MacIntire
We discuss the derivation of the so-called semi-classical equations for both mini-superspace and dilaton gravity. We find that there is no systematic derivation of a semi-classical…
