Clustering phenomena are ubiquitous with applications ranging from raindrops to galaxies, and from facebook to traffic jams. A key question we address is: how fast do clusters grow how large, and even effectively infinite?
Problems such as traffic flow have conserved quantities but no absorbing state, leading to phase separation between a localised condensate (e.g. traffic jam) and a background (e.g. flowing traffic) at critical density.
