Topological nodal line semimetals
Chen Fang, Hongming Weng, Xi Dai +1
We review the recent, mainly theoretical, progress in the study of topological nodal line semimetals in three dimensions. In these semimetals, the conduction and the valence bands…
Three-dimensional Critical Dirac semimetal in KMgBi
Congcong Le, Shengshan Qin, Xianxin Wu +3
We predicted that AMgBi (A=K,Rb Cs), which have the same lattice structures as the 111 family of iron-based superconductors (Na/LiFeAs), are symmetry-protected Dirac semimetals loc…
Co-existence of Weyl Fermion and Massless Triply Degenerate Nodal Points
Hongming Weng, Chen Fang, Zhong Fang +1
By using first-principles calculations, we propose that WC-type ZrTe is a new type of topological semimetal (TSM). It has six pairs of chiral Weyl nodes in its first Brillouin zone…
Topological Semimetals with Triply Degenerate Nodal Points in θ-phase Tantalum Nitride
Hongming Weng, Chen Fang, Zhong Fang +1
Using first-principles calculation and symmetry analysis, we propose that θ-TaN is a topological semimetal having a new type of point nodes, i.e., triply degenerate nodal points. E…
Tunable Weyl fermions and Fermi arcs in magnetized topological crystalline insulators
Junwei Liu, Chen Fang, Liang Fu
Based on analysis and realistic tight-binding calculations, we find that time-reversal-breaking Weyl semimetals can be realized in magnetically-doped (Mn, Eu, Cr etc.) S…
Diagnosis of interaction-driven topological phase via exact diagonalization
Han-Qing Wu, Yuan-Yao He, Chen Fang +2
We propose a general scheme for diagnosing interaction-driven topological phases in the weak interaction regime using exact diagonalization (ED). The scheme comprises the analysis…
