Generalized exponential model

The Generalized exponential model (or GEM-m potential) is given by (Eq. x in ):

${\mathrm{\Phi }}_{12}(r)=ϵ\exp [-{(\frac{r}{\sigma })}^m]$

where

• $r:=|{\mathbf{r}}_1-{\mathbf{r}}_2|$
• ${\mathrm{\Phi }}_{12}(r)$ is the intermolecular pair potential between two particles or sites

m=1

Also known as the EXP model .

m=4

2-dimensions .
