Generalized Uncertainty Principle, Extra-dimensions and Holography
F. Scardigli, R. Casadio
We consider Uncertainty Principles which take into account the role of gravity and the possible existence of extra spatial dimensions. Explicit expressions for such Generalized Unc…
Electromagnetic waves around dilatonic stars and naked singularities
Roberto Casadio, Sergio Fabi, Benjamin Harms
We study the propagation of classical electromagnetic waves on the simplest four-dimensional spherically symmetric metric with a dilaton background field. Solutions to the relevant…
On the gravitational collapse in anti-de Sitter space-time
G. L. Alberghi, R. Casadio
We study the semiclassical evolution of a self-gravitating thick shell in Anti-de Sitter space-time. We treat the matter on the shell as made of quantized bosons and evaluate the b…
On brane-world black holes and short scale physics
Roberto Casadio
There is evidence that trans-Planckian physics does not affect the Hawking radiation in four dimensions and, consequently, deviations from the linear dispersion relation (for massl…
Thermodynamics for radiating shells in anti-de Sitter space-time
G. L. Alberghi, R. Casadio, G. Venturi
A thermodynamical description for the quasi-static collapse of radiating, self-gravitating spherical shells of matter in anti-de Sitter space-time is obtained. It is shown that the…
Holography and trace anomaly: what is the fate of (brane-world) black holes?
Roberto Casadio
The holographic principle relates (classical) gravitational waves in the bulk to quantum fluctuations and the Weyl anomaly of a conformal field theory on the boundary (the brane).…
