Resumen:
It is known that below a certain critical temperature, driven diffusive
systems exhibit an ordered phase with striped patterns running along
the direction of the drive, while above the critical point a gas-like
disordered phase is observed. In this work, the influence of an
additional drive, applied in the direction perpendicular to the
original one, is studied and discussed. It is found that fixing the
temperature and the density of particles, the system also exhibits
orderdisorder transitions when the additional external drive is finely
tuned around some critical values. The corresponding phase diagram,
which includes both first- and second-order transitions, is analyzed.
