Quantum networks in the presence of the Rashba effect and a magnetic field

Bercioux, D. ; Governale, M. ; Cataudella, V. ; Ramaglia, V.


We use a simple formalism to calculate the conductance of any quantum network consisting of single- channel one-dimensional quantum wires in the presence of Rashba spin-orbit coupling and a coupling magnetic field. We show that the Rashba effect may give rise to an electron localization phenomenon similar to the Aharonov-Bohm effect. This localization effect can be attributed to spin precession ...
