标题： The effect of the lateral interactions on the critical behavior of long straight rigid rods on two-dimensional lattices

摘要： 使用蒙特卡罗模拟和有限尺寸标度分析，研究了在中间密度下方形晶格上长度为k（k-mer）的吸引刚性棒的临界行为。 发现了一种向列相，其特征是存在一个由平行k-mer组成的较大区域。 这种有序相通过一个发生在中间密度\theta _c 的连续转变与各向同性状态分隔开，该密度随着横向相互作用强度的增加而线性增加。 显示英文摘要

摘要： Using Monte Carlo simulations and finite-size scaling analysis, the critical behavior of attractive rigid rods of length k (k-mers) on square lattices at intermediate density has been studied. A nematic phase, characterized by a big domain of parallel k-mers, was found. This ordered phase is separated from the isotropic state by a continuous transition occurring at a intermediate density \theta_c, which increases linearly with the magnitude of the lateral interactions.
