I will present a theoretical framework to describe macroscopic properties of driven diffusive systems which are confined to narrow geometries and interact locally. These systems exhibit particle queuing/jamming phase transitions, if the influx exceeds the transport capacity. The phase transitions are determined by the dynamics of domain walls (shock waves). It can be shown that the macroscopic features of these systems can be captured by an extremal principle on the current.
This is a roughly weekly series of didactical blackboard talks focussing on some theoretical aspect of Condensed Matter, Biological, and Statistical Physics..
