Pre-Hawking radiation cannot prevent the formation of apparent horizon
Pisin Chen, William G. Unruh, Chih-Hung Wu +1
As an attempt to solve the black hole information loss paradox, recently there has been the suggestion that, due to semi-classical effects, a pre-Hawking radiation must exist durin…
Model for Quantum Effects in Stellar Collapse
Bruno Arderucio-Costa, William Unruh
We present a simple model for stellar collapse and evaluate the quantum mechanical stress-energy tensor to argue that quantum effects do not play an important role for the collapse…
Information Loss
William G. Unruh, Robert M. Wald
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 cr…
How the huge energy of quantum vacuum gravitates to drive the slow accelerating expansion of the Universe
Qingdi Wang, Zhen Zhu, William G. Unruh
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…
Scattering of a composite quasiparticle by an impurity on a lattice
Fumika Suzuki, Marina Litinskaya, William G. Unruh
We study scattering of a composite quasiparticle, which possesses a degree of freedom corresponding to relative separation between two bound excitations, by a delta-like impurity p…
