摘要: 本文首先详细介绍了场与介观约瑟夫森结相互作用系统的哈密顿量,进一步讨论了系统的量子化方案,然后简要 介绍了不变本征算符法及其基本应用.在此基础上,用不变本征算符法求得外场与介观约瑟夫森结相互作用系统的能级间隔.

关键词: 不变本征算符法, 介观约瑟夫森结, 能级间隔

Abstract: The Hamilton of the interaction system between field and a mesoscopic Josephson junction is introduced in detail.The quantization scheme of the system is discussed.The technique of“eigen-operator”and its basic application are discussed briefly.Thus the interval of energy level of mesoscopic Josephson junctions in the presence of external fields is calculated by using the technique of the eigen-operator.

Key words: technique of the eigen-operator, mesoscopic Josephson junctions, interval of energy level
