Quantum anomalous Hall effect

Quantum Anomalous Hall effect is a kind of Hall effect. It is anomalous in the sense that, unlike the usual Hall effect, it does not need external magnetic field. It is called "quantum" because it is predicted by quantum theory and occurs on a quantum scale.[1] The effect has been observed experimentally.[2][3]
