 abstract = {A colloid supported against gravitational settling by means of an
imposed electric field behaves, on average, as if it is at equilibrium
in a confining potential [T. M. Squires, J. Fluid Mech. 443, 403
(2001)]. We show, however, that the effective Langevin equation for the
colloid contains a nonequilibrium noise source, proportional to the
field, arising from the thermal motion of dissolved ions. The position
fluctuations of the colloid show strong, experimentally testable
signatures of nonequilibrium behavior, including a highly anisotropic,
frequency-dependent ``effective temperature″ obtained from the
fluctuation-dissipation ratio.},
