Hints of (trans-Planckian) asymptotic freedom in semiclassical cosmology
Corrado Appignani, Roberto Casadio
We employ the semiclassical approximation to the Wheeler-DeWitt equation in the spatially flat de Sitter Universe to investigate the dynamics of a minimally coupled scalar field ne…
Gravitational collapse of a radiating shell and radiation bursts
Roberto Casadio
We study the collapse of a self-gravitating thick shell of bosons coupled to a scalar radiation field. Due to the non-adiabaticity of the collapse, the shell (quantum) internal deg…
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…
