Perisistent Current of Dirac Sea : Application to Bismuth
スポンサーリンク
概要
- 論文の詳細を見る
Bismuth has been known to exhibit anomalously large diamagnetism which hasbeen interpreted on the basis of the effective Hamiltoxtian of the Dirac type includingspin-orbit coupling. I-Iere the persistent current in a mesoscopic ring of bismuth iscalculated. It is found that the magnetic flux induces persistent currents which have aspatial spread of tlte order of l;=2hv/E.. (r: velocity of the 'Dirac' electron; E.xenergy gap), just as in the atomic diamagnetism whose "atomic" size is gigantic andof mesoscopic scale.mesoscopic system, persistent current, Dirac equation, bismuth
