Super-inflation in Loop Quantum Cosmology
E. J. Copeland, D. J. Mulryne, N. J. Nunes +1
We investigate the dynamics of super-inflation in two versions of Loop Quantum Cosmology, one in which the Friedmann equation is modified by the presence of inverse volume correcti…
Non-linear vector perturbations in a contracting universe
Filipe C. Mena, David J. Mulryne, Reza Tavakol
A number of scalar field models proposed as alternatives to the standard inflationary scenario involve contracting phases which precede the universe's present phase of expansion. A…
Inflationary Cosmology and Oscillating Universes in Loop Quantum Cosmology
D. J. Mulryne, N. J. Nunes, R. Tavakol +1
We study oscillatory universes within the context of Loop Quantum Cosmology. We make a comparative study of flat and positively curved universes sourced by scalar fields with eithe…
Oscillatory Universes in Loop Quantum Cosmology and Initial Conditions for Inflation
James E. Lidsey, David J. Mulryne, N. J. Nunes +1
Positively-curved, oscillatory universes are studied within the context of Loop Quantum Cosmology subject to a consistent semi-classical treatment. The semi-classical effects are r…
Inflationary Cosmology and Quantization Ambiguities in Semi-Classical Loop Quantum Gravity
Martin Bojowald, James E. Lidsey, David J. Mulryne +2
In loop quantum gravity, modifications to the geometrical density cause a self-interacting scalar field to accelerate away from a minimum of its potential. In principle, this mecha…
