Resumen:
We present numerical calculations concerning the phenomenon of spin-charge separation in low-dimensional strongly correlated electron systems. Specifically, we study the t-J model on a flux-threaded ring connected to semi-infinite free-electron leads. The transmittance through such an Aharonov-Bohm ring shows an interference pattern with characteristic sharp dips at certain flux values, determined by the filling, which are a direct consequence of spin-charge separation in a nanoscopic system.
