Bosonization of 2+1 dimensional fermions on the surface of topological insulators
Andrea Cappelli, Lorenzo Maffi, Riccardo Villa
Three-dimensional topological insulators can be described by an effective field theory involving two `hydrodynamic' Abelian gauge fields. The action contains a bulk topological BF…

Hydrodynamics, anomaly inflow and bosonic effective field theory
Alexander G. Abanov, Andrea Cappelli
Euler hydrodynamics of perfect fluids can be viewed as an effective bosonic field theory. In cases when the underlying microscopic system involves Dirac fermions, the quantum anoma…
