Giant thermo-emf in multiterminal superconductor/normal-metal mesoscopic structures

We considered a mesoscopic superconductor/normal-metal (S/N) structure in which the N reservoirs are maintained at different temperatures. It is shown that in the absence of current between the N reservoirs a voltage difference V_T arises between the superconducting and normal conductors. The voltage V_T oscillates with increasing phase difference φ between the superconductors, and its magnitude does not depend on the small parameter (T/ε_F).
