Novel universality classes of a coupled driven diffusive system — •Abhik Basu and Erwin Frey — Abteilung Theorie (SF5), Hahn-Meitner-Institute, D-14109 Berlin

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 continuosly with the strength of these cross-correlations. The implications of these results for experimentally relevant systems are discussed.
