Russo-Tartaglia-Sciortino model

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

$\Phi _{12}=\left({\frac {1}{r_{12}}}\right)^{m}-\sum _{i=1}^{M_{1}}\sum _{j=1}^{M_{2}}\epsilon \exp \left[-{\frac {1}{2}}\left({\frac {r_{12}^{ij}}{\alpha }}\right)^{n}\right]$

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.
