Effective field theories for topological insulators by functional bosonization
Effective field theories that describe the dynamics of a conserved U(1) current in terms of ``hydrodynamic'' degrees of freedom of topological phases in condensed matter are discussed in general dimension $D=d+1$ using the functional bosonization technique. For noninteracting topological insulators (superconductors) with a conserved U(1) charge and characterized by an …
