Quasicrystal formation in binary soft matter mixtures
journal contribution
posted on 2020-08-21, 09:45 authored by Alberto Scacchi, WRC Somerville, DMA Buzza, Andrew ArcherAndrew ArcherUsing a strategy that may be applied in theory or in experiments, we identify
the regime in which a model binary soft matter mixture forms quasicrystals. The
system is described using classical density functional theory combined with
integral equation theory. Quasicrystal formation requires particle ordering
with two characteristic lengthscales in certain particular ratios. How the
lengthscales are related to the form of the pair interactions is reasonably
well understood for one component systems, but less is known for mixtures. In
our model mixture of big and small colloids confined to an interface, the two
lengthscales stem from the range of the interactions between pairs of big
particles and from the cross big-small interactions, respectively. The
small-small lengthscale is not significant. Our strategy for finding
quasicrystals involves tuning locations of maxima in the dispersion relation,
or equivalently in the liquid state partial static structure factors.
