Genericity of non-monotonic relaxation versus persistence time in active glasses

Determine whether the non-monotonic dependence of the relaxation time on the persistence time of the active noise observed in some self-propelled particle models is a generic feature of active systems with persistent noise or is specific to particular activity models.

Background

Several simulations have reported a re-entrant or non-monotonic variation of relaxation time with the persistence time of activity in dense active systems, while other studies show differing trends depending on the activity implementation.

Clarifying whether this behavior is universal or model-specific is crucial for developing comprehensive theories of active glass transitions.
