Reciprocal relations for nonlinear coupled transport.
Reciprocal relations are derived for transport between two pairs of reservoirs energetically coupled at mesoscopic contact points through second order in the chemical potential differences. In the derivation attention is focussed on the average number of particles transported between the reservoirs during each excursion of the contact point away from, and regression back to, a steady state. All quantities involved are experimentally accessible in the full counting statistics of the transport processes.
