Abstract：The preheating era at which inflation field oscillates after inflation includes interesting phenomena, especially non-perturbative particle production. The non-perturbative particle production is caused by the oscillating inflation field but the picture is quite different from the perturbative decay process. Such phenomenon can be applied to other situations, for example, vacuum selection, baryogenesis, etc. In this seminar, I will review the mechanism of non-perturbative particle production and talk about my relating studies.
