Abstract

We use Monte Carlo (MC) simulations to study the Coulomb forces that drive individual electrons in a two-dimensional normal electron fluid and a Wigner crystal. These forces have been previously shown to determine many-electron magnetoconductivity and cyclotron resonance of nondegenerate electron systems; they are also known to provide an important characteristic of the dynamics of particles that form a fluid. We have calculated the moments of the force distribution that are relevant for electron transport, which will permit a quantitative comparison of the many-electron transport theory with experiment. We have investigated the shape of the force distribution. Far tails of the distribution were analyzed by combining the method of optimal fluctuation with MC calculations, and the results were compared with direct MC results.
