New Aspects of Reheating
D. Boyanovsky, M. D'attanasio, H. J. de Vega +2
The reheating stage in post-inflationary cosmologies is reanalyzed. New techniques from non-equilibrium quantum field theory allow a consistent derivation of the equation of motion…
Reheating and Thermalization, Linear Vs. Non-Linear Relaxation
D. Boyanovsky, M. D'attanasio, H. J. de Vega +2
We consider the case of a scalar field, the inflaton, coupled to both lighter scalars and fermions, and the study the relaxation of the inflaton via particle production in both the…
Reheating the Post Inflationary Universe
D. Boyanovsky, M. D'Attanasio, H. J. de Vega +3
We consider the non-equilibrium evolution of the inflaton field coupled to both lighter scalars and fermions. The dissipational dynamics of this field is studied and found to be qu…
Domain Walls in a FRW Universe
D. Boyanovsky, David E. Brahm, A. Gonzalez-Ruiz +2
We solve the equations of motion for a scalar field with domain wall boundary conditions in a Friedmann-Robertson-Walker (FRW) spacetime. We find (in agreement with Basu and Vilenk…
