Quantum amplitudes in black-hole evaporation: Spins 1 and 2
A. N. St. J. Farley, P. D. D'Eath
Quantum amplitudes for at Maxwell fields and for linearised gravitational wave perturbations of a spherically symmetric Einstein/massless scalar background, describing…
Relic Radiation from an Evaporating Black Hole
A. N. St. J. Farley, P. D. D'Eath
We present a non-string-theoretic calculation of the microcanonical entropy of relic integer-spin Hawking radiation -- at fixed total energy . The only conserved macroscopic qua…
Scalar--Field Amplitudes in Black--Hole Evaporation
A. N. St. J. Farley, P. D. D'Eath
We study the quantum-mechanical decay of a Schwarzschild-like black hole into almost-flat space and weak radiation at a very late time, evaluating quantum amplitudes (not just prob…
and Sigma Models in Supergravity: Bianchi type IX Instantons and Cosmologies
M. M. Akbar, P. D. D'Eath
We find instanton/cosmological solutions with biaxial Bianchi-IX symmetry, involving non-trivial spatial dependence of the - and -sigma-models coupled to…
Classical Boundary-value Problem in Riemannian Quantum Gravity and Self-dual Taub-NUT-(anti)de Sitter Geometries
M. M. Akbar, P. D. D'Eath
The classical boundary-value problem of the Einstein field equations is studied with an arbitrary cosmological constant, in the case of a compact () boundary given a biaxial…
Loop Amplitudes in Supergravity by Canonical Quantization
P. D. D'Eath
Dirac's approach to the canonical quantization of constrained systems is applied to supergravity, with or without gauged supermatter. Two alternative types of boundary cond…
