RESEARCH

I am interested in the interplay between strongly correlated systems, such as heavy Fermion superconductors and topological nature of materials. Together with several experimental groups, including the members in this research project, I mainly work on the theoretical aspects of this interplay. My current focuses are on one of typical heavy Fermion superconductors, UPt₃ and also on superfluid ³He A and B-phases. They share a similar topological character because those superfluids are believed to be described by triplet pairing function in common.

As for UPt₃, I am now investigating the topological properties of vortices and surfaces which turn out to accommodate Majorana quasi-particles in the vortex core and the interface respectively. Thus it is urgent to consider how to detect those Majorana particles experimentally. It is my intension to investigate possible experimental methods in collaboration with the experimental groups in this project.

As for ³He superfluids I am planning to closely work with the experimentalists in this area of this project and help them to perform the best experiments in connection with their experimental missions. In particular, I try to design meaningful experiments using the rotating cryostats in ISSP, Univ. Tokyo, which are the world top facility.
