Transport by bi-harmonic drives: from harmonic to vibrational mixing
Journal of Physics: Condensed Matter, 2005 Transport in a one-dimensional symmetric device can be activated by the combination of thermal noise and a bi-harmonic drive. The results of extensive simulations allow us to distinguish between two apparently different bi-harmonic regimes: (i) harmonic mixing, where the two drive frequencies are commensurate but not too high; (ii) vibrational mixing ...
