The Gaussian overlap model was developed by Bruce J. Berne and Philip Pechukas [1] and is given by Eq. 3 in the aforementioned reference:

where , is the intermolecular pair potential, and are angle dependent strength and range parameters, and is a unit vector. Not long after the introduction of the Gaussian overlap model Stillinger [2] proposed a stripped-down version of the model, known as the Gaussian core model. For a Soft cluster crystal phase has been observed. For Note that as this potential becomes the penetrable sphere model.

Virial coefficients[edit]


Phase diagram[edit]

The phase diagram of the Gaussian-core model has been calculated by Prestipino et al.[5] while the solid-liquid phase equilibria has been calculated by Mausbach et al [6] using the GWTS algorithm.
