 abstract = {The term active nematics designates systems in which apolar elongated
particles spend energy to move randomly along their axis and interact by
inelastic collisions in the presence of noise. Starting from a simple
Vicsek-style model for active nematics, we derive a mesoscopic theory,
complete with effective multiplicative noise terms, using a combination
of kinetic theory and Ito calculus approaches. The stochastic partial
differential equations thus obtained are shown to recover the key terms
argued in Ramaswamy et al (2003 Europhys. Lett. 62 196) to be at the
origin of anomalous number fluctuations and long-range correlations.
Their deterministic part is studied analytically, and is shown to give
rise to the long-wavelength instability at onset of nematic order (see
Shi X and Ma Y 2010 arXiv:1011.5408). The corresponding nonlinear
density-segregated band solution is given in a closed form.},
