  • Title: Fluctuation dissipation relations in stationary states of interacting Brownian particles under shear.
    Author: Krüger M, Fuchs M.
    Journal: Phys Rev Lett; 2009 Apr 03; 102(13):135701. PubMed ID: 19392369.
    Abstract:
    The fluctuation dissipation theorem is studied close to the glass transition in colloidal suspensions under steady shear. Shear breaks detailed balance in the many-particle Smoluchowski equation and gives response functions in the stationary state which are smaller at long times than estimated from the equilibrium fluctuation dissipation theorem. During the final shear-driven decay, an asymptotically constant relation connects response and fluctuations, restoring the form of the fluctuation dissipation theorem with, however, a ratio different from the equilibrium one.
