Nodal surface semimetals: Theory and material realization
Weikang Wu, Ying Liu, Si Li +5
We theoretically study the three-dimensional topological semimetals with nodal surfaces protected by crystalline symmetries. Different from the well-known nodal-point and nodal-lin…

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…

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…
