The SALR ( short-range attractive - long-range repulsive) potential. This potential has a variety of functional forms.

HCDY

Plot of a region of the HCDY potential for the parameters , , , , as used in the work of Sweatman et. al. [1]

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.

This potential also goes by the names of the hard-sphere plus two Yukawa (H2Y) or hard-core double-Yukawa (HCDY) potential [2][3][4].

LJ+Y

Another SALR model consists of a generalised Lennard-Jones model in conjunction with a long-range repulsive Yukawa term [5] [6] [7]
