Dynamical Schwinger effect: Properties of the e+e− plasma created from vacuum in strong laser fields

We study the dynamical Schwinger effect in the vacuum excitation of the electron-positron plasma under action of a “laser pulse” of the simplest configuration: a linearly polarized, time-dependent and spatially homogeneous electric field. Methodical basis of this investigation is the kinetic equation which is an exact consequence of the basic equations of motion of QED in the considered field model. In the present work we investigate some features of the residual electron-positron plasma and the transient process of its formation.
