Black Hole Pair Creation and the Entropy Factor

J. David Brown

It is shown that in the instanton approximation the rate of creation of black holes is always enhanced by a factor of the exponential of the black hole entropy relative to the rate…

Lifetimes of spherically symmetric closed universes

Gregory A. Burnett

It is proven that any spherically symmetric spacetime that possesses a compact Cauchy surface and that satisfies the dominant-energy and non-negative-pressures conditions must…

Dust as a Standard of Space and Time in Canonical Quantum Gravity

J. D. Brown, K. V. Kuchar

The coupling of the metric to an incoherent dust introduces into spacetime a privileged dynamical reference frame and time foliation. The comoving coordinates of the dust particles…

A Microscopic T-Violating Optical Potential: Implications for Neutron-Transmission Experiments

J. Engel, C. R. Gould, V. Hnizdo

We derive a T-violating P-conserving optical potential for neutron-nucleus scattering, starting from a uniquely determined two-body -exchange interaction with the same symmetry.…

On Variational Principles for Gravitating Perfect Fluids

J. David Brown

The connection is established between two different action principles for perfect fluids in the context of general relativity. For one of these actions, , the fluid four--veloci…

Spin Dynamics of the LAGEOS Satellite in Support of a Measurement of the Earth's Gravitomagnetism

Salman Habib, Daniel E. Holz, Arkady Kheyfets +3

LAGEOS is an accurately-tracked, dense spherical satellite covered with 426 retroreflectors. The tracking accuracy is such as to yield a medium term (years to decades) inertial ref…

Quantum Geometrodynamics I: Quantum-Driven Many-Fingered Time

Arkady Kheyfets, Warner A. Miller

The classical theory of gravity predicts its own demise -- singularities. We therefore attempt to quantize gravitation, and present here a new approach to the quantization of gravi…

Tangent Sequences in Orlicz and Rearrangement Invariant Spaces

Pawel Hitczenko, Stephen J. Montgomery-Smith

Let (f_n) and (g_n) be two sequences of random variables adapted to an increasing sequence of -algebras such that the conditional distributions of f_n and g_n giv…

Temperature, Energy, and Heat Capacity of Asymptotically Anti-De Sitter Black Holes

J. D. Brown, J. Creighton, R. B. Mann

We investigate the thermodynamical properties of black holes in (3+1) and (2+1) dimensional Einstein gravity with a negative cosmological constant. In each case, the thermodynamic…

The Path Integral Formulation of Gravitational Thermodynamics

J. D. Brown, J. W. York

The first objective of this article is to show that the black hole partition function can be placed on a firm logical foundation by enclosing the black hole in a spatially finite "…

Closed spherically symmetric massless scalar field spacetimes have finite lifetimes

Gregory A. Burnett

The closed-universe recollapse conjecture is studied for a class of closed spherically symmetric spacetimes which includes those having as a matter source: (1) a massless scalar fi…

Asymptotic expansion for layer solutions of a singularly perturbed reaction-diffusion system

Xiao-Biao Lin

For a singularly perturbed system of reaction--diffusion equations, assuming that the 0th order solutions in regular and singular regions are all stable, we construct matched asymp…
