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…
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…
The gauge invariant effective potential: equilibrium and non-equilibrium aspects
D. Boyanovsky, D. Brahm, R. Holman +1
We propose a gauge invariant formulation of the effective potential in terms of a gauge invariant order parameter, for the Abelian Higgs model. The one-loop contribution at zero an…
Relaxation and Kinetics in Scalar Field Theories
D. Boyanovsky, I. D. Lawrie, D. S. Lee
A new approach to the dynamics of relaxation and kinetics of thermalization in a scalar field theory is presented that incorporates the relevant time scales through the resummation…
Evolution of Inhomogeneous Condensates after Phase Transitions
D. Boyanovsky, M. D'Attanasio, H. J. de Vega +1
Using the O(4) linear model, we address the topic of non-equilibrium relaxation of an inhomogeneous initial configuration due to quantum and thermal fluctuations. The space-tim…
