An international team of researchers has forced light to replicate the quantum Hall effect, a Nobel Prize–winning phenomenon that, until now, belonged almost exclusively to electrons moving through ...

The fractional quantum Hall effect is one of the most striking manifestations of strong electronic correlations and topology, traditionally requiring intense magnetic fields. Recently, experiments ...

The anomalous Hall effect displays non-monotonic temperature dependence and sign reversals, originating from the competition between short-range and long-range spin correlations and their ...
