Arrested states in persistent active matter: Gelation without attraction
Carl Merrigan, Kabir Ramola, Rakesh Chatterjee, Nimrod Segall, Yair Shokef, Bulbul Chakraborty
Abstract
The authors study phase separation and kinetic arrest in a model of self-propelled, hard-core particles with a non-convex shape, which inhibits rotations. The effects of this persistent activity resemble those of attraction, thus the phase diagram exhibits strong similarities to that of attractive colloids, exhibiting both homogeneous aging, glassy states and heterogeneous gel-like arrested states
