Chiral colour-dielectric model with perturbative quantum pions and gluons

L. R. Dodd, D. E. Driscoll

Pionic contributions to static nucleon properties are calculated in a chiral extension of the colour-dielectric model. The pion field and residual gluon field are treated perturbat…

Quantum Vacuum Instability Near Rotating Stars

A L Matacz, A C Ottewill, P C W Davies

We discuss the Starobinskii-Unruh process for the Kerr black hole. We show how this effect is related to the theory of squeezed states. We then consider a simple model for a highly…

The Coherent State Representation of Quantum Fluctuations in the Early Universe

A. L. Matacz

Using the squeezed state formalism the coherent state representation of quantum fluctuations in an expanding universe is derived. It is shown that this provides a useful alternativ…

Semi-infinite cohomology in conformal field theory and 2d gravity

Peter Bouwknegt, Jim McCarthy, Krzysztof Pilch

We discuss various techniques for computing the semi-infinite cohomology of highest weight modules which arise in the BRST quantization of two dimensional field theories. In partic…

Nonsymmetric Gravity Theories: Inconsistencies and a Cure

T. Damour, S. Deser, J. McCarthy

Motivated by the apparent dependence of string --models on the sum of spacetime metric and antisymmetric tensor fields, we reconsider gravity theories constructed from a nonsymm…

Black Holes in Higher Derivative Gravity Theories

S. Mignemi, D. L. Wiltshire

We study static spherically symmetric solutions of Einstein gravity plus an action polynomial in the Ricci scalar, , of arbitrary degree, , in arbitrary dimension, . The g…
