Description
Talk shall describe the role of light fields indirectly coupled to background during preheating. In our previous study, when we considered massless background field, we proved that non-perturbative production of states associated with such fields can be sizeable due to quantum corrections. Talk will extend this study considering massive inflaton within the interacting field formalism. It helps us with the secular growth problem observed before. Possible ways of quenching the process of preheating and analogies with instant preheating shall be presented.
