The Functional Materials Group (FMG) is a trans-divisional and interdisciplinary research group aimed at unraveling the underlying principles and unknown functionalities of diverse non-equilibrium many-body phenomena. These phenomena manifest in biological processes, chemical reactions, driven quantum materials, and nanodevices. The group conducts comprehensive research to contribute to the understanding and practical application of these phenomena. In recent years, there have been significant advancements in experimental techniques such as optogenetics, intracellular measurements, time-resolved measurements of non-equilibrium excited states, and spectroscopic measurements at the nanoscale. At the same time, there have been notable developments in computational and data science, as well as in non-equilibrium statistical mechanics. Several ISSP researchers join FMG as core members, while other members participate as concurrent members. Moreover, as a joint-use/research center, FMG actively invites external researchers to collaborate on new subjects, serving as an open platform for such collaborations.
