Dynamical scaling for probe particles in a driven fluid

Abstract
We investigate two distinct universality classes for probe particles that move stochastically in a one-dimensional driven system. If the random force that drives the probe particles is fully generated by the current fluctuations of the driven fluid, such as when the probe particles are embedded in a ring, they inherit the dynamical exponent of the fluid, which generically is z=3/2. On the other hand, if the random force has a part that is temporally uncorrelated, the resulting motion can be described by a dynamical exponent z=2 as considered in previous work.
