Query: Spin-charge separation in Aharonov-Bohm rings of interacting electrons   We investigate the properties of strongly correlated electronic models on a
flux-threaded ring connected to semi-infinite free-electron leads. The
interference pattern of such an Aharonov-Bohm ring shows sharp dips at certain
flux values, determined by the filling, which are a consequence of spin-charge
separation in a nanoscopic system.
