Techniques are developed for computing particle production due to the time dependence of a scalar field expectation
value during a phase transition. We reviewthe new version of the inflationary universe and discussbaryon production in
this model.
1. Introduction. In the big bang cosmology, the
universe may undergo a series of phase transitions as
it cools. Under such circumstances it is likely that the
universe (or some part of it) was temporarily in an
unstable or metastable field configuration and then
underwent a transition to the stable vacuum state.
