Colloids in a liquid crystal matrix exhibit very anisotropic
interactions. Further, these interactions can be altered by both properties of
the colloid and of the liquid crystal. This gives a potential for creating
specific colloidal aggregates and crystals by manipulating the interactions
between colloids. However, modelling these interacting colloids in a liquid
crystal is very challenging. We use a hybrid particle-lattice Boltzmann scheme
that incorporates hydrodynamic forces and forces from the liquid crystal
field. I will discuss configurations that we have studied,
including chains and a potentially stable colloidal crystal with a diamond
lattice structure.
