Transmittance through Aharonov-Bohm Rings: Signature of Spin-Charge Separation
نویسندگان
چکیده
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.

Conductance through strongly interacting rings in amagnetic field
We study the conductance through finite Aharonov-Bohm rings of interacting electrons weakly coupled to noninteracting leads at two arbitrary sites. This model can describe an array of quantum dots with a large charging energy compared to the interdot overlap. As a consequence of the spin-charge separation, which occurs in these highly correlated systems, the transmittance is shown to present pr...

In this paper we study the Aharonov-Bohm oscillations of transmission coefficient for an electron passing through a quantum nanoring with two identical magnetic impurities using quantum waveguide theory. It is shown that the Aharonov-Bohm oscillations are independent of the coupling constant between the electron and magnetic impurities for the singlet spin state of impurities, while for the o...

In this paper, the electronic eigenstates and energy spectra of single and two-interacting electrons confined in a concentric double quantum rings with a perpendicular magnetic field in the presence of on-center donor and acceptor impurities are calculated using the exact diagonalization method. For a single electron case, the binding energy of on-center donor and acceptor impurities ar...

In this paper, we study the electronic properties of a concentric triple quantum ring using exact diagonalization technique. The energy spectra and magnetization for a single electron and two electrons, in the presence of an applied magnetic field, are calculated and discussed. It is shown that, for two-interacting electrons, the period of Aharonov-Bohm oscillations decreases to the half of tha...
