Dynamic Behavior of Anisotropic Nonequilibrium Driving Lattice Gases
It is shown that intrinsically anisotropic nonequilibrium systems relaxing by a dynamic process exhibit universal critical behavior during their evolution toward nonequilibrium stationary states. An anisotropic scaling ansatz for the dynamics is proposed and tested numerically. Relevant critical exponents can be evaluated self-consistently using both the short- and long-time dynamics …
