      abstract     = {We study time-dependent density fluctuations in the
                      stationary state of driven diffusive systems with two
                      conserved densities ρλ. Using Monte-Carlo simulations of
                      two coupled single-lane asymmetric simple exclusion
                      processes we present numerical evidence for universality
                      classes with dynamical exponents z=(1+5√)/2 and z=3/2 (but
                      different from the Kardar–Parisi–Zhang (KPZ)
                      universality class), which have not been reported yet for
                      driven diffusive systems. The numerical asymmetry of the
                      dynamical structure functions converges slowly for some of
                      the non-KPZ superdiffusive modes for which mode coupling
                      theory predicts maximally asymmetric z-stable Lévy scaling
                      functions. We show that all universality classes predicted
                      by mode coupling theory for two conservation laws are
                      generic: they occur in two-component systems with
                      nonlinearities in the associated currents already of the
                      minimal order ρ2λρμ. The macroscopic stationary
                      current-density relation and the compressibility matrix
                      determine completely all permissible universality classes
                      through the mode coupling coefficients which we compute
                      explicitly for general two-component systems.},
