Out of Equilibrium Dynamics of an Inflationary Phase Transition
D. Boyanovsky, D. Cormier, H. J. de Vega +1
We study the non-linear dynamics of an inflationary phase transition in a quartically self coupled inflaton model within the framework of a de Sitter background. Large N and Hartre…
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…
Preheating and Reheating in Inflationary Cosmology: a pedagogical survey
D. Boyanovsky, H. J. de Vega, R. Holman +1
Recent progress in the preheating phenomena for inflationary cosmology is reviewed. We first discuss estimates of the preheating time scale and particle production at the early sta…
Reply to: Comments on ``Analytic and Numerical Study of Preheating Dynamics''
D. Boyanovsky, H. J. de Vega, R. Holman
Reply to the comment by L. Kofman, A. Linde and A.A. Starobinsky (hep-ph/9608341) to our article ``Analytic and Numerical Study of Preheating Dynamics'' (hep-ph/9608205).
Analytic and Numerical Study of Preheating Dynamics
D. Boyanovsky, H. J. de Vega, R. Holman +1
We analyze the phenomenon of preheating,i.e. explosive particle production due to parametric amplification of quantum fluctuations in the unbroken case, or spinodal instabilities i…
Inflaton Decay in De Sitter Spacetime
D. Boyanovsky, R. Holman, S. Prem Kumar
We study the decay of scalar fields, in particular the inflaton, into lighter scalars in a De Sitter spacetime background. After providing a practical definition of the rate, we fo…
