How active forces influence nonequilibrium glass transitions

Dense assemblies of self-propelled particles undergo a nonequilibrium form nitrile gloves in a bucket of glassy dynamics.Physical intuition suggests that increasing departure from equilibrium due to active forces fluidifies a glassy system.We falsify this belief by devising a model of self-propelled particles where increasing departure from equilibrium can both enhance or depress glassy dynamics, depending on the chosen state point.

We analyze a number of static and dynamic observables and suggest that the location of the nonequilibrium glass transition is primarily controlled by the evolution of two-point static density correlations due to active forces.The remtavares.com dependence of the density correlations on the active forces varies non-trivially with the details of the system, and is difficult to predict theoretically.Our results emphasize the need to develop an accurate liquid state theory for nonequilibrium systems.
