Researchers show that in one dimension, particles can have exchange statistics between bosons and fermions (anyons) whose strength can be tuned by short-range interactions; momentum-distribution measurements in existing ultracold-atom setups could observe these 1D anyons, opening a path to new forms of quantum matter and tests of fundamental quantum statistics.
Theoretical work shows that confining anyons to a single dimension forces them into two exchange types—boson-like and fermion-like—with their statistics and a measurable momentum distribution serving as a fingerprint, signaling a potential new layer of particle behavior beyond the familiar boson/fermion dichotomy.
Physicists at the Okinawa Institute of Science and Technology and the University of Oklahoma report in two Physical Review A papers that a strictly one-dimensional system can host anyons with continuously tunable exchange statistics, extending the anyon concept from two dimensions to 1D and offering a mapable recipe for these statistics.
