Electrons moving in closed loops give rise to peculiar phenomena as quantum interference. This can be controlled by applying external magnetic fields (the Aharonov-Bohm effect) or external electric fields (the Aharonov-Casher effect). The magnetic field controls interference both via orbital and Zeeman term. In this project we propose to investigate the interplay between the Rashba spin-orbit coupling and the Zeeman term in the transport properties of single channel quantum rings.
