Following the discovery of the bilayer nickel oxide La3Ni2O7, the “orbital space bilayer model”—an extension of this model—has garnered significant attention. This model relaxes the design constraints on bilayer superconductors and expands the pool of candidate materials. In this study, we designed a new material based on this model, using layered copper oxides such as YBCO as the framework. In this presentation, we will report on the theoretical evaluation of superconducting properties obtained by combining first-principles calculations and many-body electron theory, as well as the results of dynamic stability verification using phonon calculations.
