RESEARCH

I've studied superconductivity in systems without translational symmetry, in particular, superconducting junctions. I'm also interested in spin related phenomena in superconducting systems, such as proximity effect in ferromagnet/superconductor junctions. My recent main interest is topological insulator.

In this project, I will investigate superconductor without inversion symmetry, particularly symmetry of superconductivity and topology in vortex system. I'm also interested in other areas, superconductors without time-reversal symmetry and edge phenomena in spin-triplet superfluids.
