In particular, I will discuss the nature of the transition to orientational order in such systems, the properties of the ordered phase specific to the non-equilibrium nature of the problem, and candidates for continuous mesoscopic descriptions.}, keywords = {active collective fluctuations giant motion nematics statphys23 topic-5 } }
