Research Interests

The electron-nuclear correlation plays a major role in dynamial processes like a chemical reaction with an extra energy and the light-matter interaction. Such cases are called as excited state phenomena which are actually ubiquitous in nature like vision process and photosynthesis. In our research group, we are interested in the theoretical/computational description of excited state phenomena and its applications with following questions:
(a) How can we describe correlated electron-nuclear motions correctly?(b) How can we deal with chemical reactions in the excited states theoretically?(c) Based on our knowledge, how can we design functional molecular devices such as energy materials, nano-electronic/photonic devices?
So far we have achieved several things. First, we have developed a novel efficient numerical algorithm for excited state dynamics with multiple "interacting" classical trajectories. This original method outperforms the conventional approaches in a sense that it can describe the exact nuclear dynamics in the excited states as well as the correct electronic dynamics. Currently we focus on understanding chemical dynamics on excited states (such as photosynthesis and vision process) and designing novel molecular functional devices based on our approach.
