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.
摘要
基于博戈留波夫 - 德热纳理论，我们对具有能隙节点的超导体中孤立磁通线周围的低能扩展准粒子态进行了分析描述。结果表明，由于阿哈罗诺夫 - 玻姆效应，这些激发态的波函数以及相应的态密度受到与纯规范势相互作用的强烈影响。
