A primer for black hole quantum physics
Abstract The mechanisms which give rise to Hawking radiation are revealed by analyzing in detail pair production in the presence of horizons. In preparation for the black hole problem, threeExpand

The Creation of the Universe as a Quantum Phenomenon
Quantum creation of massy particles can occur in the cosmological context without cost of energy. This fact is seized upon to construct a causal open homogeneous isotropic cosmology. The universe isExpand

Hawking radiation without transPlanckian frequencies,” Phys
In a recent work, Unruh showed that Hawking radiation is unaffected by a truncation of free field theory at the Planck scale. His analysis was performed numerically and based on a hydrodynamicalExpand

Correlation energy of an electron gas at high density: plasma oscillations
The contribution from zero-point plasma oscillations to the correlation energy of an electron gas at high density is considered, using the exact high- density theory of GellMann and Brueckner and ofExpand

On the concept of time and the origin of the cosmological temperature
Time arises in the theory of gravity through the semiclassical approximation of the gravitational part of the solution of the Wheeler-De Witt equation in the manner shown by Banks (SCAG). WeExpand

Chiral Symmetry Breaking in the Action Formulation of Lattice Gauge Theory
Abstract We show, in the euclidean path-integral formulation of strong-coupling lattice gauge theory, that continuous chiral symmetry is dynamically broken, and obtain the standard current algebraExpand

On the onset of time and temperature in cosmology
It is shown how the evolution of matter is parametrized by classical time in cosmological configurations that propagate. But behind the horizon, this time becomes imaginary. In a simple model, it isExpand
