Event details

Driven systems provide examples of nonequilibrium steady states which can undergo phase transitions, even in one dimension. One class of such transitions is from a disordered to a phase separated state. I will discuss a recent conjecture proposing a criterion for the existence of phase separation in one dimensional driven systems which is believed to be widely applicable. This conjecture emerges from the correspondence between driven diffusive systems and the zero-range process - an exactly solvable model of interacting particles diffusing on a lattice.

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
