 abstract = {We construct the equations of motion for the coupled dynamics of order
parameter and concentration for the nematic phase of driven particles on
a solid surface, and show that they imply i) giant number fluctuations,
with a standard deviation proportional to the mean in dimension d=2 of
primary relevance to experiment, and ii) long-time tails similar
tot(-d/2) in the autocorrelation of the particle velocities despite the
absence of a hydrodynamic velocity field. Our predictions can be tested
in experiments on aggregates of amoeboid cells as well as on layers of
agitated granular matter.},
