The properties of hard discs in a channel (separation D) have been studied for the σ ⋜ D ⋜ 2σ regime (σ = diameter of the discs), since this regime connects the one-dimensional and two-dimensional cases which exhibit very different free energy functions. Both mechanical and computer simulation results clearly show qualitatively different states of order at low and high packing densities, respectively. A theoretical analysis of the system is presented utilizing a 'double line' model. The predicted variation of defect density versus packing density agrees phenomenologically with the results of the mechanical and computer simulations. |
