The theory provides a microscopic description of correlation-induced suppression of noise in quantum-confined systems, such as heterojunction devices. It is also capable of describing diffusive conductors in the mesoscopic regime. We discuss nonequilibrium thermal noise in a simple model of a mesoscopic wire.RevTeX, 3 pp, no figsCondensed MatterNonequilibrium Noise in Metals at Mesoscopic Scalestext
