Universality of the melting curves for a wide range of interaction potentials

We demonstrate that the melting curves of various model systems of interacting particles collapse to (or are located very close to) a universal master curve on a plane of appropriately chosen scaled variables. The physics behind this universality is discussed. An equation for the emerging “universal melting curve” is proposed. The obtained results can be used to approximately predict melting of various substances in a wide range of conditions.
