Abstract: Abstract In this study, a new P63/m type material Sr3WN3 with excellent topological nodal surface (NS) state, i.e., the conduction and valence bands cross on closed NSs in the Brillouin zone (BZ), was predicted via… read more here.

Abstract: The coexistence of non-trivial topology and superconductivity in a material may induce a novel physical phenomenon known as topological superconductivity. Topological superconductors have been the subject of intense research, yet there are severe limitations in… read more here.

Abstract: We theoretically study the three-dimensional topological semimetals with nodal surfaces protected by crystalline symmetries. Different from the well-known nodal-point and nodal-line semimetals, in these materials, the conduction and valence bands cross on closed nodal surfaces… read more here.

Abstract: Topological metals and semimetals are new states of matter which are attracting great interest in current research. Here, based on first-principles calculations and symmetry analysis, we propose that the family of titanium-based compounds ${\mathrm{Ti}}_{3}X$ ($X$=Al,… read more here.
