Nonsymmorphic-symmetry-protected hourglass Dirac loop, nodal line, and Dirac point in bulk and monolayer SiTe ( Ta, Nb)
Si Li, Ying Liu, Shan-Shan Wang +5
Nonsymmorphic space group symmetries can generate exotic band-crossings in topological metals and semimetals. Here, based on symmetry analysis and first-principles calculations, we…
Hybrid Dirac Semimetal in CaAgBi Materials Family
Cong Chen, Shan-Shan Wang, Lei Liu +4
Based on their formation mechanisms, Dirac points in three-dimensional systems can be classified as accidental or essential. The former can be further distinguished into type-I and…
Two-dimensional Spin-Orbit Dirac Point in Monolayer HfGeTe
Shan Guan, Ying Liu, Zhi-Ming Yu +3
Dirac points in two-dimensional (2D) materials have been a fascinating subject of research, with graphene as the most prominent example. However, the Dirac points in existing 2D ma…
Hourglass Dirac Chain Metal in Rhenium Dioxide
Shan-Shan Wang, Ying Liu, Zhi-Ming Yu +2
Nonsymmorphic symmetries, which involve fractional lattice translations in crystalline materials, can generate exotic types of fermionic excitations that are robust against spin-or…
Type-II nodal loops: theory and material realization
Si Li, Zhi-Ming Yu, Ying Liu +5
Nodal loop appears when two bands, typically one electron-like and one hole-like, are crossing each other linearly along a one-dimensional manifold in the reciprocal space. Here we…
