Testing string theory via black hole space-times
R. Casadio, B. Harms
Charged black holes, both spherically symmetric and rotating, in the low energy limit of string theory (Einstein-Maxwell-dilaton theory) are compared to analogous geometries in pur…

Semiclassical Quantization on Black Hole Spacetimes
R. Casadio, B. Harms, Y. Leblanc
The thermodynamical description of black holes is reviewed and critiqued. We present an alternative, microcanonical description of black holes and discuss the major differences. In…

Classical Stringy Black Holes Modify the Thermal Spectrum
B. Harms, Y. Leblanc
Non-local (alpha prime) corrections to Schwarzschild black holes are shown to invalidate the thermodynamical interpretation of black holes. In particular, the canonical and Bekenst…
