Marchesoni %J Physics %D 2000 %I arXiv %R 10.1016/S0039-6028(00)00780-9 %X A driven Brownian particle (e.g. an adatom on a surface) diffusing on a low-viscosity, periodic substrate may execute multiple jumps. In the presence of an additional periodic drive, the jump lengths and time durations become statistically modulated according to a syncronyzation mechanism reminiscent of asymmetric stochastic resonance. Here, too, bistability plays a key role, but in a dynamical sense, inasmuch as a particle switches between locked and running states. %U http://arxiv.org/abs/cond-mat/0009177v1
