Classical diffusion in random environments: A new numerical method

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

We present a numerical method for classical lattice diffusion processes in a random environment. The special merits of the presented procedure in comparison with Monte Carlo methods are in the economy of computer time and storage. As an example for the potential of the method we present results for excitation dynamics in disordered polymer chains.
