标题： Mpemba effect in the relaxation of an active Brownian particle in a trap without metastable states

摘要： 我们探讨了活性在 Mpemba 效应发生中的作用，该效应发生在一种活性胶体在没有亚稳态最小值的势能景观中扩散的系统中。 Mpemba 效应的特点是一种现象，其中较热的系统在被迅速冷却到相同低温时，比较冷的系统更快达到平衡。 虽然势能景观中的微小不对称性对于在被动胶体系统中观察此效应至关重要，但引入活性可以增强或降低这种最小不对称性的阈值，从而导致活性诱导的和抑制的 Mpemba 效应。 我们将 Mpemba 效应的变化归因于相空间中的有效平移变化，这种变化随着活性的变化而发生。 显示英文摘要

摘要： We explore the role of activity in the occurrence of the Mpemba effect within a system of an active colloid diffusing in a potential landscape devoid of metastable minimum. The Mpemba effect is characterized by a phenomenon where a hotter system reaches equilibrium quicker than a colder one when both are rapidly cooled to the same low temperature. While a minimal asymmetry in the potential landscape is crucial for observing this effect in passive colloidal systems, the introduction of activity can either amplify or reduce the threshold of this minimal asymmetry, resulting in the activity-induced and suppressed Mpemba effect. We attribute these variations in the Mpemba effect to the effective translational shift in the phase space, which occurs as activity is changed.
