RESEARCH
During my years in Tohoku University, I belonged to the group of researchers on ultra low temperature physics and heavy electron systems. It was a good fortune to join with this research group and to learn physics and the laboratory techniques. I had conducted research on fermiology using the de Haas-van Alphen (dHvA) effect at dilution refrigerator temperature. My research was centered on the material of heavy electron systems in uranium compounds which were still not popular. I elucidated on the aspects of electronic state of the heavy electron magnetic superconductor UPd2Al3. In Osaka University, while continuing the research on strongly correlated heavy electron systems, I also aimed on elucidating the anisotropy of the superconducting gap from the dHvA effect in superconducting mixed states. I had a lot of opportunities in getting to know a number of experts in Japan and abroad for joint research purposes. The relation of magnetism and superconductivity is remarkably interesting that I simply admire it, and I feel the profoundness of condensed matter physics everyday.
My main field in this project is centered on the superconducting nature in non- centrosymmetric crystal structure, especially, the nature of mixed superconductivity of different parities. In order to attain it, since the information on its anisotropic nature is mostly indispensable, I continue to grow high quality single crystals. I expect to acquire the information on the origin of the difference of spin singlet and spin triplet superconductivity. Crystals are important as stage where electrons play to produce an interesting physical property. When such stage changes, the physical property changes significantly. The lacking parity symmetry of crystal structure is a very fascinating stage. I am going to keep a point of view of 'topological quantum mechanics' on my research in order to lead a new knowledge. I am looking forward to have research discussions with other field scientists and expand my new point of view. What would really show up in limiting and controlling special conditions of electrons' motion and state…? This is the real attraction quantum condensed matter physics. I will try again to concentrate in this field.
