摘　　要：文章为纪念Josephson效应发现50周年而作.文章介绍了当前关于几种量子微结构中Josephson效应的理论研究,涉及Josephson效应的基本物理现象和它在某些热点材料中的独特表现,如单层石墨纳米条带中的0-π转变,二维拓扑绝缘体中的手征性边态超导电流,以及半导体微腔中激子极化激元凝聚体之间的Josephson效应和直流-交流Josephson电流的转变.This paper is written to commemorate the 50th anniversary of the discovery of the Josephson effect. A review is presented of recent theoretical research on the Josephson effect in several kinds of quantum microstructures, including the fundamental physical phenomenon of the Josephson effect and its peculiar features in various new materials, such as the 0-x transition in graphene nanoribbons, the chiral edge supercurrents in two-dimensional topological insulators, and the Josephson effect and DC-AC current transition between exciton polariton condensates in semiconductor microcavities.
