Abstract: The ratchet effect in the colloidal suspension moving in a narrow channel of a periodically varying diameter can be used for particle separation by sizes. We study this phenomenon by mapping the colloid in the channel onto one-dimensional lattice models in which particles stochastically jump between sites with exclusion interaction. Besides allowing multiple occupancy of sites, we consider a mixture of small and big particles as well as complex geometry of the one-dimensional lattice when each site is joined to a lateral pocket.
