Evidence for an Excitonic Insulator State in TaPdTe
Jierui Huang, Bei Jiang, Jingyu Yao +30
The excitonic insulator (EI) is an exotic ground state of narrow-gap semiconductors and semimetals arising from spontaneous condensation of electron-hole pairs bound by attractive…
Interaction Driven Topological Phase Transition in Monolayer CrCl(pyrazine)
Xuecong Ji, Jiacheng Gao, Changming Yue +4
The quadratic band crossing points (QBCPs) at Fermi level in two-dimension have been proposed to be unstable under electron-electron interaction. The possible interaction driven st…
