Phase diagram of anisotropic particles with octahedral symmetry

Artists impression of an octahedral patchy particle

The phase diagram of anisotropic particles (also known as patchy particles) that have octahedral symmetry . The octahedral symmetry is achieved via six attractive patches using the modulated patchy Lennard-Jones model.

Pressure-temperature plane

Key: fcc-o: face centred cubic (ordered), fcc-d:face centred cubic (disordered), bcc: body centred cubic and sc: simple cubic lattice.

Density-temperature plane

Key: as above.
