Local Hawking temperature for dynamical black holes

- S. Hayward, R. Criscienzo, M. Nadalini, L. Vanzo, S. Zerbini
- Physics
- 30 May 2008

A local Hawking temperature is derived for any future outer trapping horizon in spherical symmetry, using a Hamilton?Jacobi variant of the Parikh?Wilczek tunneling method. It is given by a dynamical… Expand

Tunnelling methods and Hawking's radiation: achievements and prospects

- L. Vanzo, G. Acquaviva, R. Criscienzo
- Physics
- 21 June 2011

The aim of this work is to review the tunnelling method as an alternative description of the quantum radiation from black holes and cosmological horizons. The method is first formulated and discussed… Expand

Abstract The instability against emission of massless particles by the trapping horizon of an evolving black hole is analyzed with the use of the Hamilton–Jacobi method. The method automatically… Expand

On the Unruh Effect in de Sitter Space

- R. Casadio, S. Chiodini, A. Orlandi, G. Acquaviva, R. Criscienzo, L. Vanzo
- Physics
- 15 November 2010

We give an interpretation of the temperature in de Sitter universe in terms of a dynamical Unruh effect associated with the Hubble sphere. As with the quantum noise perceived by a uniformly… Expand
