RESEARCH
I have been working on theory of the quantum transport in superconducting nanostructures.
Currently I am interested in characteristic phenomena of spin-triplet superconductors
such as the anomalous proximity effect, spin supercurrent, and unusual response to
electromagnetic field.
In this project, I am going to study quantum transport through edge states
which appear at a surface of topologically nontrivial superconductors such as
a noncentrosymmetric superconductor or a chiral one.
In addition to this, I also seek exotic phenomena peculiar to spin-triplet
superconductors in collaboration with experimental groups.
