FiniteSize Critical Behavior of the Driven Lattice Gas
Abstract
We present a detailed Monte Carlo study of the hightemperature phase of the twodimensional driven lattice gas at infinite driving field. We define a finitevolume correlation length, study its finitesizescaling behavior and extrapolate it to the infinitevolume limit by using an iterative extrapolation method. The same method is applied to the susceptibility. We determine the transverse exponents $\gamma$ and $\nu$. They turn out to be in perfect agreement with the theoretical predictions. We also compute the transverse Binder parameter, which apparently vanishes at the critical point, and the distribution of the magnetization. These results confirm the Gaussian nature of the transverse excitations.
