Entropy scaling laws in self propelled glass formers

Predicting transport from equilibrium structure is a challenging problem in liquid state physics. Here we probe glass forming composed of self-propelled “active” particles and show that increasing the duration self-propulsion makes pair excess entropy negatively larger. The associated reduction number accessible configurations per particle leads to self-diffusivity. At moderate supercooling, self-diffusivity Arrhenius reduced form obeys Dzugutov like scaling law, directly yielding us inversely proportional effective temperature. In strongly super-cooled regime, law does not apply observe that, shows non-Arrhenius (power law) dependence on temperature with an exponent depends self propulsion time active particles. To demonstrate generality our laws moderately high temperatures, set interactions be purely repulsive one case Lennard-Jones other, find both cases, reported are robust over variations propulsion. Our results may colloidal suspensions, passive tracers bacterial baths, granular media, mention few.
