Aharonov-Bohm Effect for Quasiparticles around a Vortex Line in a d-Wave Superconductor
Abstract
On the basis of the Bogoliubov-de Gennes theory we develop an analytical description of low-energy extended quasiparticle states around an isolated flux line in a superconductor with gap nodes. The wave functions of these excitations and the corresponding density of states are shown to be strongly influenced by the interaction with a pure gauge potential due to the Aharonov-Bohm scenario.
