Theory of transient response for arbitrarily strong driving fields

Abstract

A theory of the dynamical Kerr effect is developed for arbitrarily strong driving fields using a modification of the Mori equation of motion due to Grigolini et al. Using the multidimensional expansion of Grigolini and Ferrario the non-Markovian Mori equation may be written in Markov form. It is possible then to derive a macro–micro correlation theorem for the system by applying the method of Kivelson et al. In this way it is possible to bypass the linear response approximation of classical dielectric theory.
