The semiclassical electron transport in lateral surface superlattices in a magnetic field is studied by a Monte Carlo technique. The electron-electron and exchange interactions are included by a molecular-dynamics technique. It is shown that the velocity autocorrelation function exhibits a power law decay of 1/t, instead of an exponential decay, suggesting that we need to reexamine the concept of phase-breaking time by electron-electron interaction.
