Long-lived circulating currents in strongly correlated nanorings
We study the time-evolving currents flowing in an interacting ring-shaped nanostructure after a bias voltage has been switched on. The source-to-drain current exhibits the expected relaxation towards its quasistatic equilibrium value at a rate Γ_{0} reflecting the lead-induced broadening of the ring...
