The review article "Anyons in quantum Hall interferometry",written by our scientist Matteo Carrega, together with Lucia Sorba, Stefan Heun and Luca Chirolli (CNR-NANO), has just been published on the journal Nature Reviews Physics.
Recently, many researchers focussed their attention on anyons, emergent quasiparticles that are neither bosons nor fermions and possess fractional statistics. Their detection and manipulation represent key milestones in view of topologically protected quantum computation schemes.
The authors review the two main geometries of electronic interferometers developed in the Quantum Hall regime. They present interferometers basic working principles, fabrication methods and the main outcomes obtained in both the integer and the fractional QH regimes. The article also discuss on how recent technological advances led to the direct experimental demonstration of fractional statistics for Laughlin quasiparticles in a Fabry–Pérot interferometric setup.
