RESEARCH

I have been interested in boundary and impurity effects in superconductors and superfluids.
When I was a graduate student, I studied the proximity effect between a normal metal and a superconductor. After that, I have studied surface scattering effects in anisotropic BCS states, impurity effects on the dynamics of superfluid 3He in aerogel, etc.

* Anomalous quantum phenomena due to surface bound states in superfluid 3He
* Physics of proximity-induced odd-frequency Cooper pairs in superfluid 3He/aerogel composite system.
