Determining the regimes of cold and warm inflation in the susy hybrid model
Mar Bastero-Gil, Arjun Berera
The SUSY hybrid inflation model is found to dissipate radiation during the inflationary period. Analysis is made of parameter regimes in which these dissipative effects are signifi…
Dynamics of Interacting Scalar Fields in Expanding Space-Time
Arjun Berera, Rudnei O. Ramos
The effective equation of motion is derived for a scalar field interacting with other fields in a Friedman-Robertson-Walker background space-time. The dissipative behavior reflecte…
Constraining Warm Inflation with the Cosmic Microwave Background
Lisa M. H. Hall, Ian G. Moss, Arjun Berera
We discuss the spectrum of scalar density perturbations from warm inflation when the friction coefficient in the inflaton equation is dependent on the inflaton field. The spect…
Warm inflation solution to the eta-problem
Arjun Berera
Warm inflationary dynamics is shown to satisfy both the slow-roll and density perturbation constraints for or equivalently and for inflaton field amplitudes mu…
