# Chaining of hard disks in nematic needles: particle-based simulation of colloidal interactions in liquid crystals

@article{Mller2020ChainingOH, title={Chaining of hard disks in nematic needles: particle-based simulation of colloidal interactions in liquid crystals}, author={David M{\"u}ller and Tobias A. Kampmann and Jan Kierfeld}, journal={Scientific Reports}, year={2020}, volume={10} }

Colloidal particles suspended in liquid crystals can exhibit various effective anisotropic interactions that can be tuned and utilized in self-assembly processes. We simulate a two-dimensional system of hard disks suspended in a solution of dense hard needles as a model system for colloids suspended in a nematic lyotropic liquid crystal. The novel event-chain Monte Carlo technique enables us to directly measure colloidal interactions in a microscopic simulation with explicit liquid crystal…
