"Group-Theoretical Approach to Anyons, Topological Quantum Configurations, and Infinite Systems"
Classification of unitary representations of the group of diffeomorphisms of physical space, and its semidirect products, provides a unifying description of diverse quantum systems, including N-particle quantum mechanics, ordinary and exotic quantum statistics (including anyons and nonabelian anyons in two-space), and infinite configurations in statistical mechanics. The braid group enters naturally in two-space, where anyonic creation and annihilation fields satisfy \(q\)-deformed commutation relations. The ideas generalize to configurations of extended objects having nontrivial topology, albeit with various mathematically rigorous results remaining to be demonstrated. I shall review briefly the main findings, highlight some directions for investigation, and point toward a possible approach to relativistic theories based on spatial measurements in inertial reference frames. Much of this work is in collaboration with David Sharp at Los Alamos National Laboratory.
