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

The SALR ( short-range attractive - long-range repulsive) 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].
