Rashba effect in quantum networks

摘要: We present a formalism to study quantum networks made up by single-channel wires in the presence of Rashba spin-orbit coupling and magnetic field. In particular, linear transport through one-dimensional two-dimensional finite-size is studied means scattering formalism. some particular networks, action field or induces localization electron wave function. This phenomenon, which relies on both quantum-mechanical interference geometry network, manifested suppression conductance for specific values spin-orbit-coupling strength Furthermore, interplay Aharonov--Bohm phases non-Abelian phases, introduced coupling, discussed number cases.
