The 200-100 Lennard-Jones potential [1] is a variant the more well known Lennard-Jones model . It has been used to study colloids.

 \Phi_{12}(r) = 4 \epsilon \left[ \left(\frac{\sigma}{r} \right)^{200}-  \left( \frac{\sigma}{r}\right)^{100} \right]

where

  • r := |\mathbf{r}_1 - \mathbf{r}_2|
  •  \Phi_{12}(r) is the intermolecular pair potential between two particles or sites
  •  \sigma is the diameter (length), i.e. the value of r at which  \Phi_{12}(r)=0
  •  \epsilon is the well depth (energy)
