Observation of the universal magnetoelectric effect in a 3D topological insulator

Observation of the universal magnetoelectric effect in a 3D topological insulator

The electrodynamics of topological insulators has been predicted to show a new magnetoelectric term, but this hasn’t been observed. Here, Dziomet al. observe a universal Faraday rotation angle equal to the fine structure constant, evidencing the so-called topological magnetoelectric effect.
