The Mie potential was proposed by Gustav Mie in 1903 [1]. It is given by
![{\displaystyle \Phi _{12}(r)=\left({\frac {n}{n-m}}\right)\left({\frac {n}{m}}\right)^{m/(n-m)}\epsilon \left[\left({\frac {\sigma }{r}}\right)^{n}-\left({\frac {\sigma }{r}}\right)^{m}\right]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/a560ce2bd238cf1a42ca7c69fe05109929428913)
