Black Hole Thermodynamics, Casimir Effect and Induced Gravity
F. Belgiorno, S. Liberati
An analogy between the subtraction procedure in the Gibbons-Hawking Euclidean path integral approach to Horizon's Thermodynamics and the Casimir effect is shown. Then a conjecture…
Perturbations of spacetime: gauge transformations and gauge invariance at second order and beyond
Marco Bruni, Sabino Matarrese, Silvia Mollerach +1
We consider in detail the problem of gauge dependence that exists in relativistic perturbation theory, going beyond the linear approximation and treating second and higher order pe…
Two-dimensional black holes in accelerated frames: quantum aspects
R. Balbinot, A. Fabbri
By considering charged black hole solutions of a one parameter family of two dimensional dilaton gravity theories, one finds the existence of quantum mechanically stable gravitatio…
Physics with nonperturbative quantum gravity: radiation from a quantum black hole
Marcelo Barreira, Mauro Carfora, Carlo Rovelli
We study quantum gravitational effects on black hole radiation, using loop quantum gravity. Bekenstein and Mukhanov have recently considered the modifications caused by quantum gra…
Two-dimensional black holes in accelerated frames: Spacetime structure
R. Balbinot, A. Fabbri
Analytical extensions and resulting Penrose diagrams are given for the solutions of a simple 2d dilaton gravity theory describing black holes which are static as viewed by asymptot…
Quantization of a 2D Minisuperspace Model in Dilaton-Einstein Gravity
Marco Cavaglia`, Vittorio de Alfaro
We investigate a minisuperspace model of Einstein gravity plus dilaton that describes a static spherically symmetric configuration or a Kantowski - Sachs like universe. We develop…
