Nature Physics published an article entitled Observation of two types of fractional excitation in the Kitaev honeycomb magnet by members of the Condensed Matter Physics Department at Jožef Stefan Institute, Nejc Janša, Andrej Zorko, Matjaž Gomilšek, Matej Pregelj and Martin Klanjšek, and colleagues from Switzerland. The article describes the first clear confirmation of the existence of two types of anyonic quasiparticle in a layered crystal α-RuCl3, which is known as the best realization of the Kitaev honeycomb lattice. A decade old famous Kitaev prediction spurred numerous experimental efforts to confirm the existence of anyons. The discovery is important also as the braiding operations with anyons offer one of the most promising platforms for topological quantum computing.
