Finite-size scaling in the driven lattice gas / Sergio Caracciolo, Andrea Gambassi, Massimiliano Gubinelli, Andrea Pelissetto. - In: JOURNAL OF STATISTICAL PHYSICS. - ISSN 0022-4715. - 115:1-2(2004), pp. 281-322.
Abstract:
We present a Monte Carlo study of the high-temperature phase of the twodimensional
driven lattice gas at infinite driving field. We define a finite-volume
correlation length, verify that this definition has a good infinite-volume limit
independent of the lattice geometry, and study its finite-size-scaling behavior.
The results for the correlation length are in good agreement with the predictions
based on the field theory proposed by Janssen, Schmittmann, Leung, and
Cardy. The theoretical predictions for the susceptibility and the magnetization
are also well verified. We show that the transverse Binder parameter vanishes at
the critical point in all dimensions d \ 2 and discuss how such result should be
expected in the theory of Janssen et al. in spite of the existence of a dangerously
irrelevant operator. Our results confirm the Gaussian nature of the transverse
excitations.
