Work with Maskawa on Microscopic Theory of Nuclear Collective Motion

Development of theoretical study originated from a pioneering work on large-amplitude nuclear collective motion proposed at the end of the 1970's by members of a theory group, Institute for Nuclear Study, University of Tokyo is reviewed by putting special emphasis on an important contribution of Toshihide Maskawa. Thanks to his broad and deep knowledge on mathematical physics, and owing to his friendly cooperation in the theory group, a basic idea of the work was further developed, and successfully formulated in a general and lucid form, which was presented in a paper entitled Self-Consistent Collective-Coordinate Method for the Large-Amplitude Nuclear Collective Motion. Since the theory was formulated in a widely applicable, plain and terse way, it has been developed by retaining a large overlap with theoretical forefront in various fields of science. Its recent developments for exploring an evolution of matter in connection with nonlinear dynamics, non-equilibrium statistical physics and bio-chemical sciences are also discussed.
