Phys. Rev. Lett. 104, 076801 (2010) [4 pages]Mesoscopic Coulomb Drag, Broken Detailed Balance, and Fluctuation RelationsReceived 16 October 2009; published 16 February 2010 When a biased conductor is put in proximity with an unbiased conductor a drag current can be induced in the absence of detailed balance. This is known as the Coulomb drag effect. However, even in this situation far away from equilibrium where detailed balance is explicitly broken, theory predicts that fluctuation relations are satisfied. This surprising effect has, to date, not been confirmed experimentally. Here we propose a system consisting of a capacitively coupled double quantum dot where the nonlinear fluctuation relations are verified in the absence of detailed balance. © 2010 The American Physical Society URL:
