| Outline of Final Research Achievements |
The purpose of this research is to develop an efficient calculation method to analyze spin-orbit interactions in large systems such as biomolecules, based on large-scale density functional theory (DFT) calculations. Relativistic calculations including spin-orbit interactions are much more computational-cost consuming than usual non-relativistic calculations. Therefore, in this research, we have developed an efficient calculation method, which can contract primitive basis functions to be minimal while keeping the original accuracy, and succeeded in reducing the computational times of both closed- and open-shell calculations significantly.
