Quantum Decay of Domain Walls in Cosmology II: Hamiltonian Approach
Shawn J. Kolitch, Douglas M. Eardley
This paper studies the decay of a large, closed domain wall in a closed universe. Such walls can form in the presence of a broken, discrete symmetry. We study a novel process of qu…
Quantum Decay of Domain Walls In Cosmology I: Instanton Approach
Shawn J. Kolitch, Douglas M. Eardley
This paper studies the decay of a large, closed domain wall in a closed universe. Such walls can form in the presence of a broken, discrete symmetry. We introduce a novel process o…
Qualitative Analysis of Brans-Dicke Universes with a Cosmological Constant
Shawn J. Kolitch
Solutions to flat space Friedmann-Robertson-Walker cosmologies in Brans-Dicke theory with a cosmological constant are investigated. The matter is modelled as a -law perfect flui…
Behavior of Friedmann-Robertson-Walker Cosmological Models in Scalar-Tensor Gravity
Shawn J. Kolitch, Douglas M. Eardley
We analyze solutions to Friedmann-Robertson-Walker cosmologies in Brans-Dicke theory, where a scalar field is coupled to gravity. Matter is modelled by a -law perfect fluid, inc…
