Quantum Interference of Electrons in a Ring: Tuning of the Geometrical Phase
Quantum Interference of Electrons in a Ring: Tuning of the Geometrical Phase
We calculate the oscillations of the dc conductance across a mesoscopic ring, simultaneously tuned by applied magnetic and electric fields orthogonal to the ring. The oscillations depend on the Aharonov-Bohm flux and of the spin-orbit coupling. They result from mixing of the dynamical phase, including the Zeeman spin splitting, and …
