%0 Journal Article %T Modified Fluctuation-dissipation theorem for non-equilibrium steady-states and applications to molecular motors %A G. Verley %A K. Mallick %A D. Lacoste %J Physics %D 2010 %I arXiv %R 10.1209/0295-5075/93/10002 %X We present a theoretical framework to understand a modified fluctuation-dissipation theorem valid for systems close to non-equilibrium steady-states and obeying markovian dynamics. We discuss the interpretation of this result in terms of trajectory entropy excess. The framework is illustrated on a simple pedagogical example of a molecular motor. We also derive in this context generalized Green-Kubo relations similar to the ones derived recently by Seifert., Phys. Rev. Lett., 104, 138101 (2010) for more general networks of biomolecular states. %U http://arxiv.org/abs/1009.4123v3
