The Hyperbolic Bloch Equations of General Relativity
Andrew Farley
New equations are derived which describe the evolution in curved spacetime of null geodesics with non-zero (complex) shear and twist rates resembling Grishchuk's squeezed s…
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…
Coherent and squeezed states in black-hole evaporation
A. N. St. J. Farley, P. D. D'Eath
In earlier Letters, we adopted a complex approach to quantum processes in the formation and evaporation of black holes. Taking Feynman's prescription, rather than than one of…
Bogoliubov transformations for amplitudes in black-hole evaporation
A. N. St. J. Farley, P. D. D'Eath
The familiar approach to quantum radiation following collapse to a black hole proceeds via Bogoliubov transformations, and yields probabilities for final outcomes. In our (complex)…
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…
