摘要
We present here a formulation of subdynamics to calculatee Wannier-Mott excitons in a Nami-semiconductor driven by a strong electrical field. The formula of the evolution of density operator for the time-dependent Liouvillian is given. In terms of this formula rue can calculate the nonlinear response of the absorbing coefficient of light for nami-semicouducton. The results are helpful to study either the nonlinear behavior of the Wannier-Mott excitons in a nami-semicouducton driven by a strong harmonic field or the optic properties of these Kinds of materials.
