Hard disk model: Difference between revisions

Revision as of 14:48, 19 November 2007

Hard disks are hard spheres in two dimensions. The hard disk intermolecular pair potential is given by

Φ (r) = {\begin{matrix} \infty & ; & r < σ \\ 0 & ; & r \geq σ \end{matrix}

where $Φ (r)$ is the intermolecular pair potential between two disks at a distance $r$ , and $σ$ is the diameter of the disk.
