  • Title: Experimental accessibility of generalized fluctuation-dissipation relations for nonequilibrium steady states.
    Author: Mehl J, Blickle V, Seifert U, Bechinger C.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2010 Sep; 82(3 Pt 1):032401. PubMed ID: 21230123.
    Abstract:
    We study the fluctuation-dissipation theorem for a brownian particle driven into a nonequilibrium steady state experimentally. We validate two different theoretical variants of a generalized fluctuation-dissipation theorem. Furthermore, we demonstrate that the choice of observables crucially affects the accuracy of determining the nonequilibrium response from steady state nonequilibrium fluctuations.
