Decay of correlations in the regular Lorentz gas

Journal Article · · J. Stat. Phys.; (United States)
DOI:https://doi.org/10.1007/BF01010456· OSTI ID:6958359
;

The regular Lorentz gas on triangular lattice is studied numerically and analytically. The velocity correlation function is shown to decay exponentially in the number of collisions with a decay rate which vanishes as the scatterers approach close packing. The crossover to power law decay at close packing is described by a scaling function.
