论文摘要
我们介绍了冰箱的操作原理，该冰箱利用活性的布朗颗粒中的惯性效应将其（动力学）温度降低到环境温度以下两个数量级。该原理利用了惯性活性布朗颗粒的相图的特殊但较未知的形状，仅在靶向冷却状态下引发运动性诱导的相位分离。值得注意的是，活跃的冰箱可以运行，而无需隔离墙壁，以系统地吸收和陷阱，例如来自环境的有毒物质。
We present the operational principle for a refrigerator which uses inertial effects in active Brownian particles to locally reduce their (kinetic) temperature by two orders of magnitude below the environmental temperature. This principle exploits the peculiar but so-far unknown shape of the phase diagram of inertial active Brownian particles to initiate motility-induced phase separation in the targeted cooling regime only. Remarkably, active refrigerators operate without requiring isolating walls opening the route towards using them to systematically absorb and trap, e.g., toxic substances from the environment.
