Inflationary Attractors and their Measures
Alejandro Corichi, David Sloan
Several recent misconceptions about the measure problem in inflation and the nature of inflationary attractors are addressed. We show that within the Hamiltonian system of flat Fri…
Anisotropic Spinfoam Cosmology
Julian Rennert, David Sloan
The dynamics of a homogeneous, anisotropic universe are investigated within the context of spinfoam cosmology. Transition amplitudes are calculated for a graph consisting of a sing…
Loop Quantum Cosmology and the Fine Structure Constant
David Sloan
The cosmological implications of introducing a variation to the fine structure `constant', αare examined within the context of Loop Quantum Cosmology. The evolution of αis describe…
Bouncing Anisotropic Universes with Varying Constants
John D. Barrow, David Sloan
We examine the evolution of a closed, homogeneous and anisotropic cosmology subject to a variation of the fine structure 'constant', α, within the context of the theory introduced…
A Homogeneous Model of Spinfoam Cosmology
Julian Rennert, David Sloan
We examine spinfoam cosmology by use of a simple graph adapted to homogeneous cosmological models. We calculate dynamics in the isotropic limit, and provide the framework for the a…
