Notes on black-hole evaporation
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…
Experimental black hole evaporation
It is shown that the same arguments which lead to black-hole evaporation also predict that a thermal spectrum of sound waves should be given out from the sonic horizon in transsonic fluid flow.
Absorption Cross-Section of Small Black Holes
The absorption cross section of small nonrotating black holes is calculated for massive scalar and Dirac particles. The latter cross section is shown to be exactly 1/8 of the former for all energies…
Why study quantum theory
It is argued that the study of the problems associated with quantum mechanics and gravity, and especially those arising from the role of measurement in quantum gravity, have led and will continue to…
Measurement of stimulated Hawking emission in an analogue system.
TLDR
The analogy between the propagation of fields around black holes and surface waves on moving water and the measured amplitudes of the converted waves demonstrate the thermal nature of the conversion process for this system attest to the generality of the Hawking process.
Energy-momentum tensor near an evaporating black hole
We calculate the vacuum expectation value, T/sub ..mu nu../, of the energy--momentum tensor of a massless scalar field in a general two-dimensional spacetime and evaluate it in a two-dimensional…
What happens when an accelerating observer detects a Rindler particle
The nature of the interaction between a quantum field and an accelerating particle detector is analyzed from the point of view of an inertial observer. It is shown in detail for the simple case of a…
Gravity wave analogues of black holes
It is demonstrated that gravity waves of a flowing fluid in a shallow basin can be used to simulate phenomena around black holes in the laboratory. Since the speed of the gravity waves as well as…
Universality of the Hawking effect
Addressing the question of whether the Hawking effect depends on degrees of freedom at ultrahigh (e.g., Planckian) energies/momenta, we propose three rather general conditions on these degrees of…
How the huge energy of quantum vacuum gravitates to drive the slow accelerating expansion of the Universe
We investigate the gravitational property of the quantum vacuum by treating its large energy density predicted by quantum field theory seriously and assuming that it does gravitate to obey the…
