摘要：

The definition of vacuum in curved space-time is a delicate object. With Minkowski-like vacuum definition, the current has a characteristic behavior in Robertson-Walker space-time. In this work we study the behavior of Dirac current in a de Sitter spacetime. The rapid oscillations of current is observed with respect to time and indicate vigorous instability in initial vacuum and is interpreted as vigorous particle production.
