Non-Equilibrium Field Theory Dynamics in Inflationary Cosmology
D. Cormier
For simple inflationary models, we provide a consistent and complete scheme by which the macro-physical details of early universe inflation may be determined explicitly from the un…
Out of Equilibrium Fields in Inflationary Dynamics. Density Fluctuations
D. Boyanovsky, D. Cormier, H. J. de Vega +2
The energy and time scales during the inflationary stage of the universe calls for an out of equilibrium quantum field treatment. Moreover, the high energy densities involved make…
Self-Consistent Dynamics of Inflationary Phase Transitions
D. Boyanovsky, D. Cormier, H. J. de Vega +2
The physics of the inflationary universe requires the study of the out of equilibrium evolution of quantum fields in curved spacetime. We present the evolution for both the geometr…
Preheating in FRW Universes
D. Boyanovsky, D. Cormier, H. J. de Vega +3
The nonlinear time evolution of the quantum fields is studied in the O(N) model for large N in a radiation dominated FRW universe, with a view towards the phenomenon of explosive p…
