Resumen:
A set of coupled Brownian motors- resulting from a noise-induced phase transition generated
through an entropic mechanism, and formerly studied in mean-eld approximation- is numerically integrated by Heun's method. The results add much insight to the mean-eld ones, allowing interpretation of the underlying mechanisms. It turns out that the low-noise boundary of the ordered phase obtained in mean-eld approximation lies near a region where the order parameter is negative. Hints of bistability and negative mobility around F = 0 are seen in two cases, and anomalous hysteresis is conrmed in one case.
