摘　　要：拓扑物态是凝聚态物理近年来最重要的研究领域之一。随着研究的不断深入,对拓扑物态的研究逐渐从弱关联材料体系拓展到了强关联材料体系。文章梳理了近年来对拓扑近藤半金属的相关研究,介绍了其中的理论模型、计算方法和一些候选材料及实验研究,并对该方向未来的发展做了展望。Topological matter has been one of the most active research areas in condensed matter physics during the last decade.The development of this field has gradually expanded from weakly correlated to strongly correlated materials.In this paper we review studies of topological Kondo semimetals by introducing theoretical models,calculation approaches,as well as some candidate materials and their experimental studies.We also look ahead to the future development of this field.
