Wu, Yong-Shi | Braid group and anyons on a cylinder | In this paper we present a careful reexamination of anyons on a cylinder (or annulus), starting from the braid-group analysis. Proper attention is paid to the topological features arising from the existence of noncontractible loops. The rule for putting anyons on a square lattice has to be modified ... | Braid group; Annulus | 1991-02 |

Wu, Yong-Shi | Gauge invariance of fractionally charged quasiparticles and hidden topological Zn symmetry | Using the braid-group formalism we study the consequences of gauge invariance for fractionally charged anyonic quasiparticles in a two-dimensional multiply connected system. It is shown that gauge invariance requires multicomponent wave functions, and leads to the emergence of a hidden topological... | Gauge invariance; Topological Zn symmetry; Braid-group representation | 1991-02 |
