| Outline of Final Research Achievements |
We have conducted research to establish a technique to reproduce superconducting transition temperatures of hydrogen compounds and to explore new superconducting materials. We found that the superconducting transition temperature of LaH10 can be explained by quantum effects originating from the quantum fluctuation of hydrogen, and showed that the transition temperature can be reproduced quantitatively. We also studied hydrides containing sulfur and carbon, which were experimentally pointed out as possible room-temperature superconductors, and clarified that the room-temperature superconductivity cannot be explained by the conventional mechanism. We believe that these results will be indispensable knowledge in the exploration of new superconducting materials with higher transition temperatures.
