摘要:
A derivation of a density‐matrix equation of motion exact to all orders in the driving field is presented for a system of dynamically independent electrons interacting with a set of randomly distributed static scattering centers. Nonlinear ``driving'', ``collision'', and ``interference'' terms are exhibited. An expansion of the equation of motion through second order in the field is readily obtained from the exact nonlinear equation.
