Weeks-Chandler-Andersen reference system model

The Weeks-Chandler-Andersen reference system model consists of the purely repulsive part of the Weeks-Chandler-Andersen perturbation theory, i.e.

$\Phi _{\rm {repulsive}}(r)=\left\{{\begin{array}{ll}\Phi _{\rm {LJ}}(r)+\epsilon &{\rm {if}}\;r<2^{1/6}\sigma \\0&{\rm {if}}\;r\geq 2^{1/6}\sigma \end{array}}\right.$

where $\Phi _{\rm {LJ}}(r)$ represents the Lennard-Jones model.

Colloids

Has been used as a model for colloids .
