Research Topic

Group-theoretical development for dynamical transition in crystal
structures: integrating real-space and electronic topologies

Research Outline

The "crystal structure (real space)" that forms matter and the "electronic states" within it each possess characteristics of "topology," which represents the connectivity of their shapes and properties. Until now, the mainstream approach has been "static" research that treats these two aspects separately without considering changes. However, how the "dynamic process" --in which a crystal continuously transforms into another shape--affects the electronic states has not yet been sufficiently discussed from a theoretical standpoint.
Therefore, this study focuses on the "route of structural transformation" itself, aiming to integrate crystal deformation and changes in electronic states into a single, unified theory.
Specifically, we will elucidate the correlation between crystal deformation patterns and electronic states using mathematical theories, such as group theory. This work is expected to lay the foundation for a new field in condensed matter physics that anticipates material deformation and manufacturing processes.
