论文摘要
研究了环上对称硬核颗粒环境中的完全不对称的示踪剂颗粒。对于单个示踪剂，明确得出了固定状态特性，包括环境密度曲线和示踪剂速度。显示出一个以上示踪剂的系统被证明将单个示踪子系统分解为单个示踪程序，从而将单个示踪剂结果扩展到任意数量的示踪剂。我们证明了合作效应的存在，其中许多示踪剂的速度比单个示踪剂在相同的大小和密度的环境中移动。通过模拟验证了分析计算。将结果与相关系统中既定的结果进行比较。
Totally asymmetric tracer particles in an environment of symmetric hard-core particles on a ring are studied. Stationary state properties, including the environment density profile and tracer velocity are derived explicitly for a single tracer. Systems with more than one tracer are shown to factorise into single-tracer subsystems, allowing the single tracer results to be extended to an arbitrary number of tracers. We demonstrate the existence of a cooperative effect, where many tracers move with a higher velocity than a single tracer in an environment of the same size and density. Analytic calculations are verified by simulations. Results are compared to established results in related systems.
