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…
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…
The Effect of Boundaries in One-Loop Quantum Cosmology
Peter D. D'Eath, Giampiero Esposito
The problem of boundary conditions in a supersymmetric theory of quantum cosmology is studied, with application to the one-loop prefactor in the quantum amplitude. Our background c…
