Abstract:
We compare properties of the crystal structure and of the quasicrystal model
of liquid. We show that if the Lennard-Jones potential is used to model
the properties of argon, then the temperature of the phase transition between
the densely packed face-centered and the body-centered cubic structure is very
close to the liquid–crystal transition temperature. Based on this, we
propose a model of the phase transition consisting in a change of just
the short-range order, which then leads to a change of the long-range order.
