Solid-liquid coexistence of the noble elements. II. Neon, krypton and xenon

The noble elements constitute the simplest group in the periodic table. At low temperatures or high pressures, the liquid phase solidifies into a face-centered cubic crystal structure (except helium). In the companion paper, we investigated the fcc solid-liquid coexistence of argon in the light of hidden scale invariance. Here we extend the investigation to neon, argon, krypton, and xenon. Computations are done using the SAAP potential, suggested by Deiters and Sadus [J. Chem. Phys 150, 134504 (2019)], derived from accurate ab initio calculations. The systems exhibit hidden scale invariance in the investigated part of the phase diagram, which makes it possible to predict the shape and property variations along the solid-liquid coexistence lines.
