Quantum Magnetic Dynamics of Polarized Light in Arrays of Microcavities
An-Chun Ji, X. C. Xie, Wu‐Ming Liu · Physical Review Letters · 2007
We describe an optical system that allows for a direct experimental observation of the quantum magnetic correlated dynamics of polarized light. By adjusting the Zeeman and the Raman fields, we could realize a ferromagnetic phase, super-counter-fluidity phase, and antiferromagnetic phase of polarized light, that are of interest for studying spin-dependent photon-photon interactions. We also design an experimental protocol for the observation of these phases. Moreover, the technique of controlling photospin correlation may be used for building quantum information devices.
