The Effect of Multiple Scattering on Longitudinal Magnetoconductivity

Abstract

Longitudinal magnetoconductivity is calculated in a self-consistent t-matrix approximation in order to discuss the effect of multiple scattering. With the help of a generalized optical theorem, calculation of conductivity is reduced to an integral equation for the effective path. The equation is formally solved following the procedure of solving the Markov chain problem. In the quantum limit, the effect of collision broadening on longitudinal conductivity is shown negligible contrary to Dubinskaya’s conclusion.
