The quantum Hall effect: still delivering surprises

Despite having been discovered more than 45 years ago, the quantum Hall effect continues to reveal new physics. The latest development is the discovery of the fractional quantum Hall effect (FQHE) in ferromagnetically-polarized systems in the absence of an external magnetic field. The physics is that of an incompressible quantum fluid that supports fractional charge excitations with non-standard statistics, and in its “non-Abelian” variety, is in principle capable of storing and hiding quantum information non-locally in entanglement patterns. The zero-magnetic-field realizations show that initial explanations of FQHE in terms of the properties of Landau levels need to be reworked to include the new lattice-based systems.
