System with spatially periodic potential field and subject to multiplicative noise. (English) Zbl 1077.70014

Summary: The transport of particles in a spatially periodic field driven by multiplicative noise is investigated. The probability current shows that the correlation of the noise with the space is an ingredient for the net flux of particles. By two special models, we illustrate the transport induced by the multiplicative noise in the absence of spatial asymmetry.
