The `Ups' and `Downs' of a Spinning Black Hole
Chris M. Chambers, William A. Hiscock, Brett E. Taylor
We report and comment upon the principal results of an investigation into the evolution of rotating black holes emitting massless scalar radiation via the Hawking process. It is de…
Quantum effects in the Alcubierre warp drive spacetime
William A. Hiscock
The expectation value of the stress-energy tensor of a free conformally invariant scalar field is computed in a two-dimensional reduction of the Alcubierre ``warp drive'' spacetime…
Astrophysical Bounds on Global Strings
Shane L. Larson, William A. Hiscock
Global topological defects produce nonzero stress-energy throughout spacetime, and as a result can have observable gravitational influence on surrounding matter. Gravitational effe…
Spinning Down a Black Hole With Scalar Fields
Chris M. Chambers, William A. Hiscock, Brett Taylor
We study the evolution of a Kerr black hole emitting scalar radiation via the Hawking process. We show that the rate at which mass and angular momentum are lost by the black hole l…
Semiclassical effects in black hole interiors
William A. Hiscock, Shane L. Larson, Paul R. Anderson
First-order semiclassical perturbations to the Schwarzschild black hole geometry are studied within the black hole interior. The source of the perturbations is taken to be the vacu…
