AI 中文摘要
我们研究了具有Yukawa相互作用的粒子在由做圆周运动的活性手性粒子组成的介质中的直流驱动输运。驱动粒子表现出堵塞相、非线性无序或塑性状态（在该状态下，与活性手性粒子的相互作用产生有限的霍尔效应），以及高驱动线性状态（在该状态下，驱动粒子与非驱动粒子发生相分离，霍尔效应几乎消失）。手性粒子受到驱动粒子的强烈拖曳和霍尔效应，这些效应随热涨落或手性运动参数的变化而单调变化。不同的动力学相与纵向和横向输运曲线的特征相关联，我们根据活性轨道尺寸、热涨落和粒子密度绘制了相图。
英文摘要
We examine the dc driven transport of particles with Yukawa interactions through an assembly of chiral active particles undergoing circular motion. The driven particles exhibit a jammed phase, a nonlinear disordered or plastic regime where there is a finite Hall effect produced by interactions with the active chiral particles, and a high drive linear regime where the driven and nondriven particles phase separate and the Hall effect nearly disappears. The chiral particles experience strong drag and Hall effects from the driven particles, and these effects vary monotonically with changing thermal fluctuations or chiral motion parameters. The different dynamical phases are correlated with features in the longitudinal and transverse transport curves, and we map out the phases as a function of active orbit size, thermal fluctuations, and particle density.
