Russo-Tartaglia-Sciortino model

The Russo-Tartaglia-Sciortino model is given by (Eqs. 1-3):

${\mathrm{\Phi }}_{12}={(\frac{1}{r_{12}})}^m-\sum _{i=1}^{M_1}\sum _{j=1}^{M_2}ϵ\exp [-\frac{1}{2}{(\frac{r_{12}^{ij}}{\alpha })}^n]$

where $r_{12}$ is the distance between the centre of mass of particles 1 and 2, $r_{12}^{ij}$ is the distance between patches $i$ and $j$ on different particles, and $M_1$ and $M_2$ are the number of patches of particles 1 and 2 respectively.
