I have theoretically studied quantum transport phenomena in a superconducting junction consisting of a topologically nontrivial superconductor. Especially I have been focusing on physics of a spin-triplet superconductor which hosts Majorana fermions at its surface as the topologically protected bound states. Recent research interests are in the unusual superconducting phenomena caused by odd-frequency Cooper pairs.
