Huge broadening of the crystal-fluid interface for sedimenting colloids

Elshad Allahyarov, Hartmut L\"owen

Sedimenting colloidal hard spheres develop a crystal-fluid interface that splits and broadens dramatically at intermediate gravitational strengths.

Claims

C1strongest claim

The width of the crystal-amorphous-liquid interface is strongly peaked as a function of gravitational driving strength with a huge amplitude relative to its equilibrium counterpart.

C2weakest assumption

The observed splitting and huge broadening are intrinsic to the hard-sphere sedimentation dynamics rather than artifacts of the finite simulation box, periodic boundaries, or the particular Brownian-dynamics integrator.

C3one line summary

Sedimenting colloidal hard-sphere crystals exhibit a gravitationally peaked, huge broadening of the crystal-fluid interface caused by its splitting into crystal-amorphous and amorphous-liquid sub-interfaces.
