具有小表面损耗的长Josephson结中流子的运动

具有小表面损耗的长Josephson结中流子的运动 MOTION OF FLUXON IN A LONG JOSEPHSON JUNCT1ON WITH SMALL SURFACE LOSSES 徐济仲 Xu Jizhong first-author 本文用线性微扰法讨论了有小的表面损耗存在时的流子行为,并给出了流子的经典速度与绝热速度的近似表示式;在一级近似下我们找到了稳态时偏流与速度的关系,并与实验结果进行了比较。 In this paper we have discussed the behavior of fluxon in the presence of small surface losses by linear perturbation theory. The approximate ex-pressions of the classical velocity and the adiabatic velocity of fluxon are found. The relation between bias current and velocity in the steady-state is given and is compared with experiment. 表面损耗 Josephson结 流子 经典速度 绝热速度 surface losses Josephson junction fluxon classical velocity adiabatic velocity. 中国科学院科学基金 1988-03-01 2021-04-01 3
