Spin-charge separation in Aharonov-Bohm rings of interacting electrons
arXiv:cond-mat/0406319 · doi:10.1103/PhysRevLett.93.067203
Abstract
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.
