Title:
Sr2RuO4 - A textbook case of an unconventional superconductor

講師:
Prof. Manfred Sigrist （京都大学 基礎物理学研究所　教授）

日時・場所:
5月17日 (月) 16:00-17:00
大学院講義室（理学 2 号館 2-2-11)にて

要旨：　The order parameter in unconventional superconductors can appear in various forms and the first task for each new system of this kind is to determine its particular symmetry. For Sr2RuO4 experiment and theory seem to fit well together identifying one clear strong candidate for pairing state: d =nz(kx+iky) or nz(kx-iky) . This spin-triplet pairing state is consistent with all presently available experiments and has various unusual properties. This talk focuses on the experimental status and various properties of this p-wave pairing state. Some specific subjects addressed are: the anomalous behavior and selection rules of the Josephson effect, the quasiparticle states at the surface and at domain walls and the mechanism for p-wave pairing. It will be shown that Sr2RuO4 incorporates many of the exotic aspects of an unconventional superconductor and might serve as the example in future textbooks.
