Yang-Mills Cosmologies and Collapsing Gravitational Sphalerons
G. W. Gibbons, Alan R. Steif
Cosmological solutions with a homogeneous Yang-Mills field which oscillates and passes between topologically distinct vacua are discussed. These solutions are used to model the col…
The Quantum Stress Tensor in the Three Dimensional Black Hole
Alan R. Steif
The quantum stress tensor is calculated in the 2+1 dimensional black hole found by Banados, Teitelboim, and Zanelli. The Greens function, from which is deriv…
Ultra--Planck Scattering in D=3 Gravity Theories
S. Deser, J. McCarthy, Alan R. Steif
We obtain the high energy, small angle, 2-particle gravitational scattering amplitudes in topologically massive gravity (TMG) and its two non-dynamical constituents, Einstein and C…
Anomalous Fermion Production in Gravitational Collapse
G. W. Gibbons, Alan R. Steif
The Dirac equation is solved in the Einstein-Yang-Mills background found by Bartnik and McKinnon. We find a normalizable zero-energy fermion mode in the -wave sector. As shown r…
