论文摘要
限制在一维通道的Janus流体的平衡特性是完全得出的。流体是由具有两个面（主动和被动）的颗粒制成的，因此两对相互作用是硬球的相互作用，除非两个活跃的面在彼此的前面，在这种情况下，相互作用具有方形 - 孔孔有吸引力的尾巴。我们的精确解决方案是指淬火的系统（即每个粒子都有固定的面向取向），但是我们通过统计机械工具来争辩，结果也适用于在热力学极限中的退火系统（即，每个粒子都可以翻转其方向）。分别为淬火和退火系统的理论结果与蒙特卡洛模拟之间的比较表明了极好的一致性。
The equilibrium properties of a Janus fluid confined to a one-dimensional channel are exactly derived. The fluid is made of particles with two faces (active and passive), so that the pair interaction is that of hard spheres, except if the two active faces are in front of each other, in which case the interaction has a square-well attractive tail. Our exact solution refers to quenched systems (i.e., each particle has a fixed face orientation), but we argue by means of statistical-mechanical tools that the results also apply to annealed systems (i.e., each particle can flip its orientation) in the thermodynamic limit. Comparison between theoretical results and Monte Carlo simulations for quenched and annealed systems, respectively, shows an excellent agreement.
