In particular, (1) a model that explains the correlation of the transition temperature of superconductors with the proximity of their electronic structure to the Lifshitz topological transition will be constructed and an algorithm for finding superconductors with higher critical temperatures will be proposed; (2) the influence of multiband on phase coherence and interference phenomena in superconductors will be modeled and the related features of transport and microwave properties of such materials will be revealed; (3) the role of interband transitions in the enhancement of superconductivity at interfaces will be determined and the optimal contact geometry for selection in new superconducting quantum interferometers will be selected. popup.nrat_date 2024-12-10 Close
