Three nondissipative forces on a moving vortex line in superfluids and superconductors
Volovik G.E.
In the hydro dynamic limit the nondissipative force Tndt which acts on the vortex in superconductors and Fermi superfluids, contains three different contributions of the topological origin. These are (i) the Magnus force, (ii) the Iordanskii force, which origin is analogous to the Aharonov-Bohm effect for the spinning cosmic strings, and (Hi) the force resulting from the spectral flow of fermion zero modes in the vortex core, which leads to the production of the momentum of quasipartides when the vortex moves with respect to the normal component. The latter force leads to the anomaly in the thermodynamics of the moving vortices, and the possible relation of this anomaly to the Unruh effect is discussed.
