Query: Phase diagram of Kob-Andersen type binary Lennard-Jones mixtures   The binary Kob-Andersen (KA) Lennard-Jones mixture is the standard model for
computational studies of viscous liquids and the glass transition. For very
long simulations the viscous KA system crystallizes, however, by phase
separating into a pure A particle phase forming an FCC crystal. We present the
thermodynamic phase diagram for KA-type mixtures consisting of up to 50\% small
(B) particles showing, in particular, that the melting temperature of the
standard KA system at liquid density $1.2$ is $1.028(3)$ in A particle
Lennard-Jones units. At large B particle concentrations the system crystallizes
into the CsCl crystal structure. The eutectic corresponding to the FCC and CsCl
structures is cut-off in a narrow interval of B particle concentrations around
26\% at which the bipyramidal orthorhombic ${\rm PuBr_3}$ structure is the
thermodynamically stable phase. The melting temperature's variation with B
particle concentration at two other pressures, as well as at the constant
density $1.2$, is estimated from the simulations at pressure $10.19$ using
isomorph theory. Our data demonstrate approximate identity between the melting
temperature and the onset temperature below which viscous dynamics appears.
Finally, the nature of the solid-liquid interface is briefly discussed.
