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

TL;DR

This paper shows that the melting curves of diverse particle interaction models can be unified into a single universal curve using scaled variables, aiding in predicting melting behavior across different substances.

Contribution

It introduces a universal master curve for melting, derived from scaled variables, and discusses the underlying physics behind this universality.

Findings

Melting curves of various systems collapse onto a universal curve.

A proposed equation describes the universal melting curve.

Results enable approximate melting predictions for different substances.

Abstract

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.
