Phys. Rev. Lett. 98, 210601 (2007) [4 pages]Einstein Relation Generalized to NonequilibriumReceived 27 December 2006; published 22 May 2007 The Einstein relation connecting the diffusion constant and the mobility is violated beyond the linear response regime. For a colloidal particle driven along a periodic potential imposed by laser traps, we test the recent theoretical generalization of the Einstein relation to the nonequilibrium regime which involves an integral over measurable velocity correlation functions. © 2007 The American Physical Society URL:
