    "abstract": "We show how a medium, under the influece of a coherent control field which is\nresonant or close to resonance to an appropriate atomic transition, can lead to\nvery strong asymmetries in the propagation of unpolarized light when the\ndirection of the magnetic field is reversed. We show how EIT can be used to\nmimic effects occuring in natural systems and that EIT can produce very large\nasymmetries as we use electric dipole allowed transitions. Using density matrix\ncalculations we present results for the breakdown of the magnetic field\nreversal symmetry for two different atomic configurations.",
