Relaxation of the additivity condition on the interaction length between unlike species in a binary mixture of soft disks opens up a rich variety of structures in both crystal and amorphous states with an associated diverse range of relaxation dynamics. We report on MD simulation studies of binary soft disks with negative deviations from additivity that include evidence of accumulation of crystal-like structures in metastable liquids prior to crystallization and the occurrence of a liquid to…

The crystal phases that can be expected from the self-assembly of mixtures of spherical particles of two different sizes are explored, which are mapped to (additive or non-additive) hard-disk mixtures and a rich variety of periodic crystal structures are found.

The structural relaxation of the random tiling phase is quantified and it is shown that this relaxation is well described by a model based on the distribution of waiting times for each atom to be visited by the diffusing zipper.
