A simple diatomic potential that prevents crystallization in supercooled liquids simulations

Abstract

We study a simple and versatile diatomic potential function coined to prevent crystallization in supercooled liquids. We show that the corresponding liquid does not crystallize even with very long simulation runs at the lowest temperature that we can access with ergodic simulations. The medium displays the usual features of supercooled materials and a non-Arrhenius dependence of the diffusion coefficient and alpha relaxation time with temperature. We also observe the breakdown of the Stokes-Einstein relation at low temperatures.
