The complete gravitational collapse of a body in general relativity will result in the formation
of a black hole. Although the black hole is classically stable, quantum particle creation …

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 …

The Unruh effect states that a uniformly linearly accelerated observer with proper acceleration
a experiences Minkowski vacuum as a thermal state in the temperature T lin = a / ( 2 π ) , …

When ground-state atoms are accelerated and the field with which they interact is in its normal
vacuum state, the atoms detect Unruh radiation. We show that atoms falling into a black …

The Unruh effect predicts a thermal response for an accelerated detector moving through
the vacuum. Here we propose an interferometric scheme to observe an analogue of the …

Einstein's theory of gravity is reformulated so that the cosmological constant becomes an
integration constant of the theory, rather than a" coupling" constant. However, in the …

The effect of the environment on a quantum system is studied on an exactly solvable model:
a harmonic oscillator interacting with a one-dimensional massless scalar field. We show that …

Abstract Models of cosmological inflation are plagued with a severe and seemingly unavoidable
problem: in order to produce density perturbations of an amplitude consistent with large-…

It is shown that the Bekenstein limit, SE≤ 2 π 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 …

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 …
