Novel universality classes of coupled driven diffusive systems.
Motivated by the phenomenologies of dynamic roughening of strings in random media and magnetohydrodynamics, we examine the universal properties of driven diffusive system with coupled fields. We demonstrate that cross correlations between the fields lead to amplitude ratios and scaling exponents varying continuously with the strength of these cross correlations. The implications of these results for experimentally relevant systems are discussed.
