The SALR ( short-range attractive - long-range repulsive) potential. This potential has a variety of functional forms.
The SALR potential is often expressed as a hard core of diameter , along with combination of two Yukawa potentials:
where is the intermolecular pair potential, is the distance between site 1 and site 2. The control is the energy of the repulsive and attractive parts, whilst the controls the interaction range.
