Observing one-dimensional anyons: Exotic quasiparticles in the coldest corners of the universe

Researchers inject an impurity into a one-dimensional ultracold gas, thereby generating a quasiparticle with exotic properties.

Scientists led by Hanns-Christoph Nägerl have observed anyons — quasiparticles that differ from the familiar fermions and bosons — in a one-dimensional quantum system for the first time. The results, published in Nature, may contribute to a better understanding of quantum matter and its potential applications.

Nature categorizes particles into two fundamental types: fermions and bosons. While matter-building particles such as quarks and electrons belong to the fermion family, bosons typically serve as force carriers — examples include photons, which mediate electromagnetic interactions, and gluons, which govern nuclear forces...
