On the Hawking effect [PDF]

open access: yes, 2000
In terms of the Painlev{\'e}-Gullstrand-Lema{\^\i}tre coordinates a rather general scenario for the gravitational collapse of an object and the subsequent formation of a horizon is described by a manifestly $C^\infty$-metric.

On Slow Light as a Black Hole Analogue [PDF]

open access: yes, 2003
Although slow light (electromagnetically induced transparency) would seem an ideal medium in which to institute a ``dumb hole'' (black hole analog), it suffers from a number of problems.

Hadamard state in Schwarzschild-de Sitter spacetime [PDF]

open access: yes, 2014
We construct a state in the Schwarzschild-de Sitter spacetime which is invariant under the action of its group of symmetries. Our state is not defined in the whole Kruskal extension of this spacetime, but rather in a subset of the maximally extended ...

Birth of a quasi-stationary black hole in an outcoupled Bose–Einstein condensate

open access: yesNew Journal of Physics, 2014
We study the evolution of an initially confined atom condensate, which is progressively outcoupled by gradually lowering the confining barrier on one side. The goal is to identify protocols that best lead to a quasi-stationary sonic black hole separating

Quantum circuit model for non-inertial objects: a uniformly accelerated mirror

open access: yesNew Journal of Physics, 2017
We develop a quantum circuit model describing unitary interactions between quantum fields and a uniformly accelerated object in two spacetime dimensions, and apply it to a semi-transparent mirror that uniformly accelerates in the Minkowski vacuum.

Reply Comment on "Entropy of 2D black holes from counting microstates" [PDF]

open access: yes, 1999
We show that the arguments proposed by Park and Yee against our recent derivation of the statistical entropy of 2D black holes do not apply to the case under considerationComment: 3 pages, LaTex file, reply to comment hep-th ...

The thermodynamic properties of Reissner-Nordstrom-de sitter black hole with quintessence

open access: yesNuclear Physics B
Recently, numerous investigations have revealed that AdS black holes exhibit fundamental characteristics similar to those of ordinary thermodynamic systems. The thermodynamic properties of multi-horizon spacetimes with different Hawking temperatures have

Dielectric black hole analogues

open access: yes, 2001
Alternative to the sonic black hole analogues we discuss a different scenario for modeling the Schwarzschild geometry in a laboratory - the dielectric black hole.

Advantages and disadvantages of maximally entangled states in dilaton black hole background

open access: yesPhysics Letters B
We investigate quantum entanglement and coherence for four classes of Bell-like fermionic states in the vicinity of the event horizon of a Garfinkle-Horowitz-Strominger (GHS) dilaton black hole. Contrary to the common expectation that maximally entangled

Hawking radiation in an electro-magnetic wave-guide?

open access: yes, 2004
It is demonstrated that the propagation of electro-magnetic waves in an appropriately designed wave-guide is (for large wave-lengths) analogous to that within a curved space-time -- such as around a black hole.
