The phase diagram of the Lennard-Jones model.
2 dimensions[edit]
3 dimensions[edit]
A very nice example of the phase diagram in the density-temperature plane is given in Figure 3 of [2], and on the pressure-temperature plane in Figure 6 of [3].
4 dimensions[edit]
Metastable phase[edit]
Solid phase[edit]
The Lennard-Jones potential has been known to form either hexagonal close-packed (hcp) or face-centred-cubic (fcc) structure. [6] Recently it has been shown that the ground state structure strongly depends on pressure, cutoff radius and the potential truncation method; and stacking sequences (polytypes) other than fcc and hcp can be the ground state structure too, e.g. dhcp, 9R...etc. [7].
