Active Chiral Nematics — •Rüdiger Kürsten1,2,3 and Demian Levis1,21Departament de Física de la Matèria Condensada, Universitat de Barcelona, Barcelona, Spain — 2Universitat de Barcelona Institute of Complex Systems (UBICS), Barcelona, Spain — 3Institut für Physik, Universität Greifswald, Greifswald, Germany

We study inherently chiral self-propelled particles in two dimensions that are subjected to nematic alignment interactions and rotational noise. By means of both, homogeneous and spatially resolved mean field theory we identify various different flocking states. We confirm the presence of the predicted phases using agent-based simulations. We emphasize that special care has to be taken within the simulations in order to avoid artifacts. We present a non-standard simulation technique in order to avoid those artifacts.
