STRONG FIELD GENERALIZATION OF THE INTERBAND TRANSITIONS KINETICS

摘要

A nonperturbative kinetic equation (KE) for description of two-band transitions under action of a strong time-dependent electric field is obtained for arbitrary dispersion laws of carriers in the c- and v-zones (the previously analogical KE was obtained in [1] for the case of quadratic mirror symmetric dispersion laws). The developed approach is based on the similarity to the dynamical Schwinger effect and considers the creation and annihilation processes as the coherent one.
