Abstract
Starting from symmetry considerations, we derive the generic hydrodynamic equation of nonequilibrium XY spin systems with N-atic symmetry under weak fluctuations. Through a systematic
treatment we demonstrate that, in two dimensions, these systems exhibit two types of scaling
behaviours. For N = 1, they have long-range order and are described by the flocking phase of dry
polar active fluids. For all other values of N, the systems exhibit quasi long-range order, as in the
equilibrium XY model at low temperature.
