Vortex motion in Fermi superfluids and the Callan-Harvey effect
Volovik G. E.
The spectral flow along the anomalous branches of the fermions, which is localized in the core of a quantized vortex in Fermi superfluids, defines at low temperatures the parameter Df which characterizes the reactive force between the vortex and the system of normal fermions. This reversible momentum exchange between coherent condensate motion in three dimensions and the one-dimensional motion of the localized fermions is equivalent to the Callan-Harvey process of the anomaly cancellation. The number of anomalous branches is related to the vortex winding number.
