We report on speeding-up equilibrium recovery in the previously unexplored general case of the underdamped regime using an optically levitated particle. We accelerate the convergence toward equilibrium by an order of magnitude compared to the natural relaxation time. We then discuss the efficiency of the studied protocols, especially for a multidimensional system. These results pave the way for optimizing realistic nanomachines with application to sensing and developing efficient nanoheat engines.
我们报告了在之前未探索过的欠阻尼状态的一般情况下，使用光悬浮粒子加速平衡恢复的情况。与自然弛豫时间相比，我们将向平衡的收敛速度加快了一个数量级。然后，我们讨论了所研究协议的效率，特别是对于多维系统。这些结果为优化应用于传感的实际纳米机器和开发高效纳米热机铺平了道路。
