Bose Condensation and Jamming Transitions

Event details

Systems driven out of equilibrium can often exhibit behaviour not seen in systems in thermal equilibrium-- for example in phase transitions in one-dimensional systems. In this talk I will review several 'condensation' transitions that occur when a conserved quantity is driven through the system. Although the condensation is spatial, i.e. a finite fraction of the conserved quantity condenses into a small spatial region, useful comparison can be made with usual Bose-Einstein condensation. The transitions can also be viewed as 'jamming transitions'. Amongst some one-dimensional examples I will discuss the 'Bus Route Model' where the condensation (jamming) corresponds to the clustering together of buses moving along a bus-route. O. J.

About Condensed Matter lunchtime seminars

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..
