【 摘 要 】

We consider a metallic wire coupled to two metallic electrodes via two junctions placed nearby. A bias voltage applied to one of such junctions alters the electron distribution function in the wire in the vicinity of another junction, thus modifying both its noise and the Coulomb blockade correction to its conductance. We evaluate such interaction corrections to both local and nonlocal conductances, demonstrating nontrivial Coulomb anomalies in the system under consideration. Experiments on nonlocal electron transport with Coulomb effects can be conveniently used to test inelastic electron relaxation in metallic conductors at low temperatures.
