| Outline of Final Research Achievements |
By applying chaos theory developed in the field of celestial mechanics into microscopic chemical reactions, we predicted theoretically that a discrete switching between the reaction/non-reaction coordinate emerges as the total energy increases, and provided an experimental means to prove this unknown phenomenon. From experimentally observed, single molecule time series whose signal-to-noise ratio is low, we developed data-driven mathematical science to reconstruct the underlying information such as network structures and energy landscapes with properly elucidating the measurement errors and errors arising from finiteness of the data, and confirmed their versatility experimentally.
