1/2-Anyons in small atomic Bose-Einstein condensates
arXiv:cond-mat/0103251 · doi:10.1103/PhysRevLett.87.010402
Abstract
We discuss a way of creating, manipulating and detecting anyons in rotating Bose-Einstein condensates consisting of a small number of atoms . By achieving a quasidegeneracy in the atomic motional states we drive the system into a 1/2--Laughlin state for fractional quantum Hall bosons. Localized 1/2--quasiholes can be created by focusing lasers at the desired positions. We show how to manipulate these quasiholes in order to probe directly their 1/2--statistics.
