@article{Arnold2012MagneticfieldinfluencedNT, title={Magnetic-field-influenced nonequilibrium transport through a quantum ring with correlated electrons in a photon cavity}, author={Thorsten Arnold and Chi‐Shung Tang and Andrei Manolescu and Vidar Gudmundsson}, journal={Physical Review B}, year={2012}, volume={87}, pages={035314} }

We investigate magnetic-field-influenced time-dependent transport of Coulomb interacting electrons through a two-dimensional quantum ring in an electromagnetic cavity under nonequilibrium conditions described by a time-convolutionless non-Markovian master equation formalism. We take into account the full electromagnetic interaction of electrons and cavity photons. A bias voltage is applied to semi-infinite leads along the $x$ axis, which are connected to the quantum ring. The magnetic field is…
