Enhancement of current commensurate with mutual noise-noise correlation in a symmetric periodic substrate: The benefits of noise and nonlinearity

► Exploration of directed transport in stochastic systems with embedded nonlinearity. ► Formalism is valid for open system in the presence of arbitrary periodic potential. ► Effective temperature depends on correlation time and extent of correlation. ► Study of the directed motion in presence of external cross-correlated noises. ► Steady state current increases with increase in the extent of correlation.
