 | Wu, Yong-Shi | Braid group, gauge invariance, and topological order | Topological order in two-dimensional systems is studied by combining the braid group formalism with a gauge invariance analysis. We show that flux insertions (or large gauge transformations) pertinent to the toroidal topology induce automorphisms of the braid group, giving rise to a unified algebrai... | Braid group; Topological order; Zero temperature; Two-dimensional systems | 2006-07 |
