论文摘要
我们研究了两个组件系统的二维Langevin动力学，该系统的组件与保持在不同温度下的热浴接触。动态受到光学陷阱的约束， \文本{不同的}物种通过二次潜能相互作用。我们意识到该系统朝着具有非零卷曲的非零概率电流朝向特殊的非平衡稳态，因此随机移动的粒子在自身周围旋转，例如“旋转顶部”玩具。我们的分析表明，旋转运动是相关的，并且还揭示了不同物种概率电流的空间成分的新兴合作行为。
We study the two-dimensional Langevin dynamics of a two-component system, whose components are in contact with heat baths kept at different temperatures. Dynamics is constrained by an optical trap and the \text{dissimilar} species interact via a quadratic potential. We realize that the system evolves towards a peculiar non-equilibrium steady-state with a non-zero probability current possessing a non-zero curl, such that the randomly moving particles are spinning around themselves, like "spinning top" toys. Our analysis shows that the spinning motion is correlated and also reveals an emerging cooperative behavior of the spatial components of the probability currents of dissimilar species.
