Outline of Final Research Achievements

We have theoretically studied the nonequilibrium phase transitions that can be induced by periodic driving in various quantum many-body systems such as topological materials, quantum magnets, strongly correlated electron systems (Mott insulator), as well as the QCD vacuum. Although the target of the research were diverse, we had a very simple and common idea. This is "Floquet engineering", i.e., control of materials through periodic driving forces.
