Beyond the Semiclassical Description of Black Hole Evaporation

- Physics
- 2002

In the semiclassical treatment, i.e. in a classical black hole geometry, Hawking quanta emerge from trans-Planckian configurations because of scale invariance. There is indeed no scale to stop the…

A note on black-hole entropy, area spectrum, and evaporation

- Physics
- 2011

A model based on the topology change of a quantum manifold is used to explain the origin of the black-hole thermodynamics. We show that this model can explain the origin of the black-hole entropy,…

- Physics
- 2012

We describe the black hole evaporation process driven by the dynamical evolution of the quantum gravitational degrees of freedom resident at the horizon, as identified by the Loop Quantum Gravity…

Hawking radiation as tunneling from a Vaidya black hole in noncommutative gravity

- Physics
- 2010

In the context of a noncommutative model of coordinate coherent states, we present a Schwarzschild-like metric for a Vaidya solution instead of the standard Eddington-Finkelstein metric. This leads…

The background field approximation in (quantum) cosmology

- Physics
- 2000

We analyse the Hamilton-Jacobi action of gravity and matter in the limit where gravity is treated at the background field approximation. The motivation is to clarify when the Wheeler-DeWitt equation…

Hawking radiation from Feynman diagrams

- Physics
- 1999

The aim of this letter is to clarify the relationships between Hawking radiation and the scattering of light by matter falling into a black hole. To this end we analyze the S-matrix elements of a…

Parikh-Wilczek tunneling from noncommutative higher dimensional black holes

- Physics
- 2009

We study tunneling of massless and massive particles through the smeared quantum horizon of the extra-dimensional Schwarzschild black holes. The emission rate of the particles' tunneling is modified…

Tunneling method for Hawking radiation in the Nariai case

- Physics
- 2017

We revisit the tunneling picture for the Hawking effect in light of the charged Nariai manifold, because this general relativistic solution, which displays two horizons, provides the bonus to allow…

Notes on black-hole evaporation

- Physics
- 1976

This paper examines various aspects of black-hole evaporation. A two-dimensional model is investigated where it is shown that using fermion-boson cancellation on the stress-energy tensor reduces the…

The off-shell black hole

- Physics
- 1995

The standard (Euclidean) action principle for the gravitational field implies that for spacetimes with black-hole topology, the opening angle at the horizon and the horizon area are canonical…

Entropy, area, and black hole pairs.

- PhysicsPhysical review. D, Particles and fields
- 1995

We clarify the relation between gravitational entropy and the area of horizons. We first show that the entropy of an extreme Reissner-Nordstr\"om black hole is zero, despite the fact that its horizon…

Internal geometry of an evaporating black hole.

- PhysicsPhysical review letters
- 1994

It is found that the evaporation process is in fact the shrinking of a throat that connects a macroscopic interior ``universe" to the asymptotically flat exterior, which confirms dynamically that black holes do evaporate thermally.

The validity of the Background Field Approximation

- Physics
- 1997

In the absence of a tractable theory of quantum gravity, quantum matter field effects have been so far computed by treating gravity at the Background Field Approximation. The principle aim of this…

Hawking radiation without trans-Planckian frequencies.

- PhysicsPhysical review. D, Particles and fields
- 1995

The mathematical and physical origin of Unruh's result is revealed, an alternative truncation scheme which may be more appropriate for black hole physics is proposed and analyzed and the thermal Hawking radiation remains unaffected even though trans-Planckian energies no longer appear.

PHYSICAL INTERPRETATION OF BLACK HOLE EVAPORATION AS A VACUUM INSTABILITY

- Physics
- 1992

Using tunneling concepts which account for particle production in the cases of an accelerated detector and a static electric Field in Minkowski space, the more elusive case of black hole evaporation…

Acceleration radiation and the generalized second law of thermodynamics

- Physics
- 1982

It is shown that the Bekenstein limit, S/E< or =2..pi..R, for the entropy-to-energy ratio of matter confined by a box of size R is not needed for the validity of the generalized second law of…
