Exciton polariton modes of a planar resonator in magnetic fields — •Steffen Richter, Chris Sturm, Helena Franke, Rüdiger Schmidt-Grund, and Marius Grundmann — Universität Leipzig, Institut für Experimentelle Physik II, Linnéstr. 5, 04103 Leipzig, Germany

Exciton-polaritons have gained large interest during the last years especially due to their ability to undergo Bose-Einstein-like condensation. Magnetic fields are important as they can be be used to control the polariton and resonator properties, e.g. in order to decrease condensation thresholds. Here, we show a theoretical study of the evolution of the polariton eigenmodes and their polarization properties (pseudo spin) in a planar resonator in the presence of a magnetic field. Thereby no restrictions of the direction of the magnetic field with respect to the polariton wave vectors are assumed. A 4×4 transfer matrix approach enables numerical application of the respective mode conditions with full polarization treatment at arbitrary in-plane wavevectors.
