Abstract

This study examines the transverse and longitudinal properties of hard disks confined in narrow channels. Employing an exact mapping of the system onto a one-dimensional polydisperse, nonadditive mixture of hard rods with equal chemical potentials, we compute various thermodynamic properties, including the transverse and longitudinal equations of state, along with their behaviors at both low and high densities. Structural properties are analyzed using the two-body correlation function and the radial distribution function, tailored for the highly anisotropic geometry of this system. The results are corroborated by computer simulations.

探索强约束硬盘流体中的各向异性压力和空间相关性:精确结果
本研究探讨了封闭在狭窄通道中的硬磁盘的横向和纵向特性。通过将该系统精确映射到化学势相等的一维多分散非相加硬棒混合物上,我们计算了各种热力学性质,包括横向和纵向状态方程,以及它们在低密度和高密度下的行为。我们使用二体相关函数和径向分布函数分析了结构特性,这些函数是针对该系统高度各向异性的几何形状量身定制的。计算机模拟证实了这些结果。

期刊介绍: Physical Review E (PRE), broad and interdisciplinary in scope, focuses on collective phenomena of many-body systems, with statistical physics and nonlinear dynamics as the central themes of the journal. Physical Review E publishes recent developments in biological and soft matter physics including granular materials, colloids, complex fluids, liquid crystals, and polymers. The journal covers fluid dynamics and plasma physics and includes sections on computational and interdisciplinary physics, for example, complex networks.
