The particular research-field for me is theoretical and computational chemistries to deal with non-adiabatic transition phenomena resulting from the "break" of the Born-Oppenheimer approximation. This field has been historically quite old, and a number of researchers from around the world are working on it. Among them, the world famous formula is "Landau-Zener formula." If you search "Landau-Zener formula", the explanation could appear on Wikipedia, but it would be found "This article may be too technical for most readers to understand ..." and it is understood as a difficult problem. On the other hand, a Japanese and a Chinese theoreticians were successfully able to solve this formula analytically (Zhu-Nakamura formula). However, overseas researchers do not readily acknowledge their results, and always go into a hot debate battle. (If you look at who in the world was the first person to solve this problem, you can easily see the truth, but I hate it because it has a political smell.)
In our laboratory, by using the Zhu-Nakamura formula, the nonadiabatic phenomenon is solved more accurately and easily, and it is applied to the nonadiabatic phenomenon in solution and the photoisomerization reaction in protein, and we theoretically reproduce the measurement and predict various phenomena observed in prior to the experiment, the paper published in 2015 quantitatively predicted the photoisomerization problem of cyclohexadiene, which is the backbone of photochromic molecules. And at the international conference held in 2018, the prediction was verified by experiments and I was very happy. Although our theoretical chemists would be happy to know that experimental chemists say “there is no point in conducting experiments any longer from experimental researchers”, I personally want experimentalists to always confirm in experiments.
