Abstract: The behavior of the dc component of the current along a quantum loop of tight-binding electrons threaded by a magnetic flux that varies linearly in time ${\ensuremath{\Phi}}_{M}(t)=\ensuremath{\Phi}t$ is investigated. We analyze the electron transport in different kinds of one-dimensional structures bended into a ring geometry: a clean one-dimensional metal, a chain with a two-band structure, and a disordered chain. Inelastic scattering events are introduced through the coupling to a particle reservoir. We use a theoretical treatment based in Baym-Kadanoff-Keldysh nonequilibrium Green's function, which allows us to solve the problem exactly.
