我们研究了具有吸引力相互作用的流体通用模型中的非平衡泳道形成，即由两种相反方向驱动的粒子组成的二维伦纳德-琼斯流体。对各种参数进行布朗动力学模拟，并辅以基于动态密度泛函理论的稳定性分析，我们确定了存在吸引力时车道形成的一般特征，包括结构特性。事实上，我们发现了多种状态（与纯排斥系统相比），以及均质相的车道和长波长不稳定性（例如分层和凝聚）之间的密切关系。
We investigate nonequilibrium lane formation in a generic model of a fluid with attractive interactions, that is, a two-dimensional Lennard-Jones fluid composed of two particle species driven in opposite directions. Performing Brownian dynamics simulations for a wide range of parameters, supplemented by a stability analysis based on dynamical density functional theory, we identify generic features of lane formation in the presence of attraction, including structural properties. In fact, we find a variety of states (as compared to purely repulsive systems), as well as a close relation between laning and long-wavelength instabilities of the homogeneous phase such as demixing and condensation.
