From Fermi's Golden Rule to the Vacuum Rabi Splitting: Magnetopolaritons in a Semiconductor Optical Microcavity

Abstract

We show that magnetic quantization of the carrier free motion into discrete Landau levels for quantum wells inserted in a Fabry-Pérot microcavity allows continuous tuning of the electromagnetic interaction from the weak coupling regime (irreversible regime described by Fermi's golden rule) to the strong coupling regime (where coherent time dependence and the vacuum Rabi splitting prevail).
