Field-dependent collision frequency of the two-dimensional driven random Lorentz gas
Field-dependent collision frequency of the two-dimensional driven random Lorentz gas
In the field-driven, thermostated Lorentz gas the collision frequency increases with the magnitude of the applied field due to long-time correlations. We study this effect with computer simulations and confirm the presence of nonanalytic terms in the field dependence of the collision rate as predicted by kinetic theory.
