This research focuses on developing an analysis code that enables high-precision evaluation of physical properties for the exploration of novel superconducting materials. Electronic state analysis based on first-principles band calculations is essential for elucidating material properties and predicting new superconductors. By combining this with the Fluctuation-Exchange (FLEX) approximation—a simulation technique grounded in many-body electron theory—it becomes possible to explore candidate materials without referring experimental data. In this framework, the superconducting transition temperature can be predicted by solving the linearized Eliashberg equation and evaluating its eigenvalues. The code is being developed in the fast and highly extensible Julia language. In the presentation, we will outline the structure of the code and provide performance benchmarks.
