Complex Paths and Covariance of Hawking Radiation in 2D Stringy Black Holes
Elias C. Vagenas
Hawking radiation is computed in different coordinate systems using the method of complex paths. In this procedure the event horizon of the 2D Schwarzschild stringy black hole is t…
Semiclassical Corrections to the Bekenstein-Hawking entropy of the BTZ Black Hole via Self-Gravitation
Elias C. Vagenas
Hawking radiation is viewed as a tunnelling process. In this way the effect of self-gravitation gives rise to semiclassical corrections to the entropy of the (2+1) BTZ black hole.…
Two-Dimensional Dilatonic Black Holes and Hawking Radiation
Elias C. Vagenas
Hawking radiation emanating from two-dimensional charged and uncharged dilatonic black holes - dimensionally reduced from (2+1) spinning and spinless, respectively, BTZ black holes…
Casimir Effect in 2D Stringy Black Hole Backgrounds
T. Christodoulakis, G. A. Diamandis, B. C. Georgalas +1
We consider the two-dimensional "Schwarzschild" and "Reissner-Nordstrom" stringy black holes as systems of Casimir type. We explicitly calculate the energy-momentum tensor of a mas…
