摘要：

Basic properties of the quantum dot structure, which is a normal region created inside superconducting matter on a subnanometer scale, are predicted theoretically. The bound states change dramatically as the number of the magnetic flux quanta changes by one. We have clarified the origin of the ''nearly midgap states'' by intuitive consideration based on the unified picture of interference of the quasiparticle proposed by Kashiwaya.
