title = "Many-body effects in quantum rings: From the Aharonov-Bohm transport to the quantum Hall regime",
abstract = "We present our recent theoretical findings on the physics of semiconductor quantum rings containing several interacting electrons. Using time-dependent density-functional theory we show that the interactions preserve the Aharonov-Bohm oscillations in quantum transport as a function of the magnetic flux, whereas increasing the ring width strongly suppresses the oscillations. Secondly, we demonstrate that various quantum Hall states in quantum rings can be characterized in a consistent way.",
