The ramp model, proposed by Jagla [1] and sometimes known as the Jagla model, is described by:
where is the intermolecular pair potential, , and .
Graphically, one has:
where the red line represents an attractive implementation of the model, and the green line a repulsive implementation.
Critical points
The liquid-vapour critical point is located at (Ref. 4)
The liquid-liquid critical point is located at (Ref. 4)
