# Fermi-Jagla model

The **Fermi-Jagla model** is a smooth variant of the Jagla model. It is given by (Eq. 1 in ^{[1]}):

There is a relation between the Fermi function and hyperbolic tangent:

Using this relation one can show that Fermi-Jagla model is equivalent to the generalised Fomin potential (which has scientific priority).
