The effect of the lateral interactions on the critical behavior of long straight rigid rods on two-dimensional lattices
arXiv:0911.3295 · doi:10.4279/pip.010005
Abstract
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 θ_c, which increases linearly with the magnitude of the lateral interactions.
