On the Description of Quantum Vortices in Superfluid Films
Abstract
The dynamics of vortices in a superfluid film at the absolute zero of temperature is studied. The quantum-mechanical, i.e., ``first-quantized'' description is compared to a recently proposed quantum-field-theoretic, i.e., ``second-quantized'' description. The theory, consisting of the nonrelativistic effective action of phonons linearly coupled to a Chern-Simons term, is used to calculate the one-loop amplitude for the elastic scattering of phonons from a vortex.
