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 theExpand

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.

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 toExpand

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 energiesExpand

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-dimensionalExpand

Measurement of stimulated Hawking emission in an analogue system.
Hawking argued that black holes emit thermal radiation via a quantum spontaneous emission. To address this issue experimentally, we utilize the analogy between the propagation of fields around blackExpand

Experimental black hole evaporation
The physicist who 35 years ago proposed the construction of “dumb holes” to search for the analog of Hawking radiation is impressed by the recent experiment that looked for entangled thermalExpand

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 ofExpand

Acceleration radiation and the generalized second law of thermodynamics
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 ofExpand

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 asExpand
