摘要
We use molecular dynamics to study the structure around two spherical colloidal particles embedded in a nematic liquid crystal host. By studying nematic ordering in the region between the two particles we are able to examine the effects of the presence of multiple particles on a nematic. In addition, we study the forces on the particles as functions of the separation between the two colloidal particles and their orientation with respect to the nematic director.
