| Research Abstract |
I theoretically investigated novel quantum condensation phenomena in the fermion systems which are localized by the randomness(for electrons) or by the trap potential(for cold atom gases). I obtained the following three outstanding results ;(1) I clarified the mechanism of superconductor-insulator transition due to the competition between Anderson localization and superconductivity.(2) I discovered the new FFLO superfluid phases in the cold atom gases.(3) I determined the order parameter of spin triplet superconductor with random spin-orbit coupling.
