Node-line Dirac semimetal manipulated by Kondo mechanism in nonsymmorphic CePtSi
Hao-Tian Ma, Xing Ming, Xiao-Jun Zheng +4
Dirac node lines (DNLs) are characterized by Dirac-type linear crossings between valence and conduction bands along one-dimensional node lines in the Brillouin zone (BZ). Spin-orbi…
