      abstract     = {Using mode-coupling theory and dynamical Monte Carlo
                      simulations, we investigate the scaling behavor of the
                      dynamical structure function of a two-species asymmetric
                      simple exclusion process, consisting of two coupled
                      single-lane asymmetric simple exclusion processes. We
                      demonstrate the appearance of a superdiffusive mode with
                      dynamical exponent z=5/3 in the density fluctuations, along
                      with a Kardar-Parisi-Zhang mode with z=3/2; we argue that
                      this phenomenon is generic for short-ranged driven diffusive
                      systems with more than one conserved density. When the
                      dynamics is symmetric under the interchange of the two
                      lanes, a diffusive mode with z=2 appears instead of the
                      non-Kardar-Parisi-Zhang superdiffusive mode.},
