On the Description of Quantum Vortices in Superfluid Films | | Joerg P. Kottmann
; Adriaan M. J. Schakel
; | | Date: |
12 Aug 1998 | | Subject: | cond-mat | | Affiliation: | Freie Universitaet Berlin | | 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. | | Source: | arXiv, cond-mat/9808133 | | Services: | Forum | Review | PDF | Favorites | |
