| Research Abstract |
The ultimate purpose of this project is to understand in depth the hierarchical structures seen in the theoretical descriptions of physical systems, by faithfully studying the dynamics in the actual physical processes, to extract key notions that are essential in connecting different layers in the hierarchy. In particular, on the dynamics of microscopic systems under the influence of the environmental system, we have proposed new ideas to keep or recover quantum coherence against environmental disturbances like decoherence or dissipation, applied them to several physical situations and obtained new knowledge on such systems. A hint to understand the relationship between the quantum field theory and the quantum mechanics has also been found.
