Triangular anisotropies in driven diffusive systems: Reconciliation of up and down
Triangular anisotropies in driven diffusive systems: Reconciliation of up and down
Deterministic coarse-grained descriptions of driven diffusive systems (DDS) have been hampered by apparent inconsistencies with the kinetic Ising models of DDS. In the evolution towards the driven steady-state, "triangular" anisotropies in the two systems point in opposite directions with respect to the drive field. We show that this is nonuniversal …
