@article{Jonasson2011QuantumMO, title={Quantum magneto-electrodynamics of electrons embedded in a photon cavity}, author={O. Jonasson and Chi‐Shung Tang and Hsi-Sheng Goan and Andrei Manolescu and Vidar Gudmundsson}, journal={New Journal of Physics}, year={2011}, volume={14} }

We investigate the coupling between a quantized electromagnetic field in a cavity resonator and a Coulomb interacting electronic system in a nanostructure in an external magnetic field. The effects caused by the geometry of the electronic system and the polarization of the electromagnetic field are explicitly taken into account. Our numerical results demonstrate that the two-level system approximation and the Jaynes–Cummings model remain valid in the weak electron–photon coupling regime, while…
