G. Kunstatter, BLACK-HOLE ENTROPY AND QUANTUM-MECHANICS IN GENERIC 2-D DILATON GRAVITY, International journal of modern physics D, 5(6), 1996, pp. 665-678
We review some recent work concerning the classical thermodynamics and
quantum mechanics of charged black holes in generic 2-D dilaton gravi
ty. The main result that has emerged from this work is an intriguing c
onnection between the classical black hole entropy and the imaginary p
art of the WKB phase of energy and charge eigenstates in the correspon
ding quantum theory.
