Effective gauge theories of superfluidity with topological order

We discuss the low-energy dynamics of superfluidity with topological order in (3+1) spacetime dimensions. We generalize a topological BF theory by introducing a non-square K matrix, and this generalized BF theory can describe massless Nambu-Goldstone bosons and anyonic statistics between vortices and quasiparticles. We discuss the general structure of discrete... Show more
