Emulation of magneto-optic Faraday effect using ultracold atoms

Abstract

We propose an arresting scheme for simulating the famous Faraday effect in ultracold atomic gases. Inspired by the similarities between the light field and the bosonic atoms, we represent the light propagation in medium by the atomic transport in accompany of the laser-atom interaction. The artificial magneto-optic Faraday effect is readily signaled by the spin imbalance of atoms, with the setup of laser fields offering a high controllability for quantum manipulation. Our proposal can be realized with current experimental techniques of ultracold atoms, and is quite promising for exploring and investigating the magneto-optic Faraday effect and associated physics.
