Photonic Quantum Hall

The Quantum Hall effect, in addition to being observed in two-dimensional electron systems, can be observed in photons. Photons do not posses inherent electric charge, but through the manipulation of discrete optical resonators and quantum mechanical phase, therein creates an artificial magnetic field^[1].This process can be expressed through a metaphor of photons bouncing between multiple mirrors. By shooting the light across multiple mirrors, the photons are routed and gain additional phase proportional to their angular momentum. This creates an effect like they are in a magnetic field.
