Decoherence of Black Holes by Hawking Radiation
J. -G. Demers, C. Kiefer
We discuss in detail the semiclassical approximation for the CGHS model of two-dimensional dilatonic black holes. This is achieved by a formal expansion of the full Wheeler-DeWitt…
Decoherence of the Unruh Detector
J. - G. Demers
As it is well known, the Minkowski vacuum appears thermally populated to a quantum mechanical detector on a uniformly accelerating course. We investigate how this thermal radiation…
Black Hole Entropy and Renormalization
Jean-Guy Demers, Rene Lafrance, Robert C. Myers
Using a new regulator, we examine 't Hooft's approach for evaluating black hole entropy through a statistical-mechanical counting of states for a scalar field propagating outside t…
Black Hole Entropy without Brick Walls
J. - G. Demers, R. Lafrance, R. C. Myers
We present evidence which confirms a suggestion by Susskind and Uglum regarding black hole entropy. Using a Pauli-Villars regulator, we find that 't Hooft's approach to evaluating…
