Persistent currents in mesoscopic Hubbard rings with spin-orbit interaction.

چکیده
The effect of spin-orbit interaction on persistent currents in mesoscopic Hubbard rings threaded by an Aharonov-Bohm flux is investigated putting stress on the orbital magnetism. The non-perturbative treatment of the spin-orbit interaction developed by Meir et al. is combined with the Bethe ansatz solution to deal with this problem exactly. We find that the interplay of spin-orbit interaction and electron-electron interaction plays a crucial role, bringing about some new effects on the orbital magnetism.

Recovery of the persistent current induced by the electron-electron interaction in mesoscopic metallic rings
Persistent currents in mesoscopic metallic rings induced by static magnetic fields are investigated by means of a Hamiltonian which incorporates diagonal disorder and the electron-electron interaction through a Hubbard term (U). Correlations are included up to second order perturbation theory which is shown to work accurately for U of the order of the hopping integral. If disorder is not very s...
متن کاملDiamagnetic orbital response of mesoscopic silver rings.
We report measurements of the flux-dependent orbital magnetic susceptibility of an ensemble of 10(5) disconnected silver rings at 217 MHz. Because of the strong spin-orbit scattering rate in silver this experiment is a test of existing theories on ensemble averaged persistent currents. Below 100 mK the rings exhibit a magnetic signal with a flux periodicity of h/2e consistent with averaged pers...
متن کاملPersistent spin currents in mesoscopic Haldane-gap spin rings
Using a modified spin-wave approach, we show that in the presence of an inhomogeneous magnetic field or an in-plane inhomogeneous electric field a mesoscopic antiferromagnetic Heisenberg ring with integer spin ~i.e., a Haldane-gap system! exhibits a persistent circulating spin current. Due to quantum fluctuations the current has a finite limit on the order of (2gmB)c/L at zero temperature, prov...
متن کاملPersistent spin current in a mesoscopic hybrid ring with spin-orbit coupling.
We investigate the equilibrium property of a mesoscopic ring with a spin-orbit interaction. It is well known that, for a normal mesoscopic ring threaded by a magnetic flux, the electron acquires a Berry phase that induces the persistent (charge) current. Similarly, the spin of an electron acquires a spin Berry phase traversing a ring with a spin-orbit interaction. It is this spin Berry phase th...
متن کاملDirectional dependence of spin currents induced by Aharonov-Casher phase
We have calculated the persistent spin current of an open ring induced by the Aharonov-Casher phase. For unpolarized electrons there exist no persistent charge currents, but persistent spin currents. We show that, in general, the magnitude of the persistent spin current in a ring depends on the direction of the direct current flow from one reservoir to another. The persistent spin current is mo...
