Scale Invariant Spectrum from Variable Speed of Light Metric in a Bimetric Gravity Theory
M. A. Clayton, J. W. Moffat
An approximately scale invariant spectrum generating the seeds of structure formation is derived from a bimetric gravity theory. By requiring that the amplitude of the CMB fluctuat…
Fluctuation Spectrum from a Scalar-Tensor Bimetric Gravity Theory
M. A. Clayton, J. W. Moffat
Predictions of the CMB spectrum from a bimetric gravity theory (gr-qc/0101126) are presented. The initial inflationary period in BGT is driven by a vanishingly small speed of gravi…
Nonlocal regularization of abelian models with spontaneous symmetry breaking
M. A. Clayton
We demonstrate how nonlocal regularization is applied to gauge invariant models with spontaneous symmetry breaking. Motivated by the ability to find a nonlocal BRST invariance that…
Causality, shocks and instabilities in vector field models of Lorentz symmetry breaking
M. A. Clayton
We show that that vector field-based models of the ether generically do not have a Hamiltonian that is bounded from below in a flat spacetime. We also demonstrate that these models…
A scalar-tensor cosmological model with dynamical light velocity
M. A. Clayton, J. W. Moffat
The dynamical consequences of a bimetric scalar-tensor theory of gravity with a dynamical light speed are investigated in a cosmological setting. The model consists of a minimally-…
Vector field mediated models of dynamical light velocity
M. A. Clayton, J. W. Moffat
A vector-tensor theory of gravity that was introduced in an earlier publication is analyzed in detail and its consequences for early universe cosmology are examined. The multiple l…
