Persistent currents in mesoscopic Hubbard rings with spin-orbit interaction.
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 a...
متن کاملConductance of Mesoscopic Rings
In the studies of conductance of closed mesoscopic systems, semi-linear response theory (SLRT) offers a novel unified framework that goes beyond the traditional Kubo formulation. In this Thesis we apply SLRT to two types of mesoscopic systems. The first is disordered quasi-1d rings, where we build an analytical model to understand the departure of SLRT results from Kubo results. Guided by the n...

متن کاملConductance oscillations in mesoscopic rings: Microscopic versus global phase
The phase of Aharonov-Bohm oscillations in mesoscopic diffusive metal rings in the presence of a magnetic field, can be modulated by the application of a dc-bias current Idc . We address the question of how a variation of Idc and hence of the microscopic phases of the electronic wave functions results in the observable ‘‘global’’ phase of the conductance oscillations. Whereas the first one can ...
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...
