Ordered active matter is typically characterized by giant density fluctuations. Nonequilibrium absorbing phase transition can suppress fluctuations resulting in hyperuniform states. Here the authors present the interplay between these phenomena in a model of active nematics coupled to an absorbing phase transition, showing a crossover between enhancement and suppression of fluctuations emerging at different length scales.

For sufficiently high density, the pair distribution function of the one-dimensional hard-sphere fluid shows a crossover in its decay from algebraic to exponential as increases. This crossover is interpreted as a signal of incipient solidlike order in one dimension, despite the absence of a true phase transition.
