Anisotropic Finite-Size Scaling Analysis of a Two-Dimensional Driven Diffusive System

Extensive Monte Carlo simulation results of the standard two-dimensional driven diffusive systems are obtained using a multispin coding technique. The nonequilibrium phase transition is analyzed with anisotropic finite-size scaling, both at the critical point and off the critical point. The field-theoretical values of critical exponents fit the data well. (TeX file size 22kBytes, figures 24kBytes)
