We show that this system can be exploited as an optical analogue of relativistic quantum electrodynamics, offering a remarkable route to access the exotic properties of massless Dirac fermions with cold atoms experiments. In particular we show that the underlying Minkowski space-time can also be modified, reaching anisotropic regimes where a remarkable anomalous quantum Hall effect and a squeezed Landau vacuum could be observed.", "revisions": [ { "version": "v3", "updated": "2009-07-14T14:13:43.000Z" } ], "analyses": { "subjects": [ "67.85.Lm", "37.10.Jk", "73.43.-f", "71.10.Fd" ], "keywords": [ "anomalous quantum hall effect", "non-abelian optical lattices", "dirac fermions", "cold atoms experiments", "relativistic quantum electrodynamics" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
