Designing a protocol to efficiently drive a stochastic system is an active field of research. Here we extend such control theory to an active Ornstein-Uhlenbeck particle (AOUP) in a bistable potential, driven by a harmonic trap. We find that protocols designed to minimize the excess work (up to linear response) perform better than naive protocols with constant velocity for a wide range of protocol durations.
设计一个能有效驱动随机系统的协议是一个活跃的研究领域。在此,我们将这种控制理论扩展到一个处于双稳势中的有源奥恩斯坦 - 乌伦贝克粒子(AOUP),该粒子由一个谐波陷阱驱动。我们发现,在广泛的协议持续时间范围内,旨在最小化额外功(直至线性响应)的协议比具有恒定速度的简单协议表现更好。
