Local Hawking temperature for dynamical black holes
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 dynamicalExpand
Tunnelling methods and Hawking's radiation: achievements and prospects
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 discussedExpand
Hamilton-Jacobi tunneling method for dynamical horizons in different coordinate gauges
Previous work on dynamical black hole instability is further elucidated within the Hamilton–Jacobi method for horizon tunneling and the reconstruction of the classical action by means of the nullExpand
Black Hole Entropy for Two Higher Derivative Theories of Gravity
TLDR
The dark energy issue is attracting the attention of an increasing number of physicists all over the world. Expand
Unruh–DeWitt Detectors in Spherically Symmetric Dynamical Space-Times
In the present paper, Unruh–DeWitt detectors are used in order to investigate the issue of temperature associated with a spherically symmetric dynamical space-times. Firstly, we review theExpand
Functional Determinants in Higher Derivative Lagrangian Theories
Motivated by the considerable success of alternative theories of gravity, we consider the toy model of a higher derivative Lagrangian theory, which reduces, in the Gaussian approximation, to theExpand
Fermion tunneling from dynamical horizons
The instability against emission of fermionic particles by the trapping horizon of an evolving black hole is analyzed and confirmed using the Hamilton-Jacobi tunneling method. This methodExpand
Functional Determinants in Higher Derivative Lagrangian Theories
Motivated by the considerable success of alternative theories of gravity, we consider the toy model of a higher derivative Lagrangian theory, namely the Pais-Uhlenbeck oscillator studied in a recentExpand
On the Hawking radiation as tunneling for a class of dynamical black holes
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 automaticallyExpand
On the Unruh Effect in de Sitter Space
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 uniformlyExpand
