Phys. Rev. Lett. 99, 183602 (2007) [4 pages]Quantum Magnetic Dynamics of Polarized Light in Arrays of MicrocavitiesReceived 20 June 2007; published 1 November 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. © 2007 The American Physical Society URL:
