Preheating after Multi-field Inflation
arXiv:0809.3455 · doi:10.1016/j.nuclphysbps.2009.07.050
Abstract
In this note I study preheating after multi-field inflation to assess the feasibility of parametric resonance. An intuitive argument for the suppression of resonances due to dephasing of fields in generic multi-field models is presented. This effect is absent in effective single field models, rendering them inappropriate for the study of preheating.
