Using overdamped Brownian dynamics simulations we investigate the isotropic- nematic (IN) transition of self-propelled rods in three spatial dimensions. For two well- known model systems (Gay-Berne potential and hard spherocylinders) we find that turning on activity moves to higher densities the phase boundary separating an isotropic phase from a (nonpolar) nematic phase. This active IN phase...
