Study of quantum phenomena in mesoscopic superconductors

When the scale of a material is comparable to one of its characteristic lengths, it is possible to exhibit physical properties different from macroscopic scale samples. Studying material systems at various mesoscopic scales will greatly deepen our understanding of the physical nature of materials and expand our understanding of physical laws. In the study of mesoscopic scale superconductors, since superconductors have some characteristic lengths, such as coherence length and superconducting penetration depth, the properties of superconductors will exhibit size effects when the scale of samples is comparable to these lengths. Superconductors with mesoscopic artificial structures exhibit abundant physical content, but many physical phenomena are still waiting for us to explore.
