Essentially degenerate hidden nodal lines in two-dimensional magnetic layer groups
Xiao-Ping Li, Chaoxi Cui, Lei Wang +4
According to the theory of group representations, the types of band degeneracy can be divided into accidental degeneracy and essential degeneracy. The essentially degenerate nodal…
Two-dimensional double-kagome-lattice nitrogene: a direct band gap semiconductor with nontrivial corner state
Wenzhang Li, Qin He, Xiao-Ping Li +2
Based on first-principles calculations, we predict that nitrogen atoms can assemble into a single-layer double kagome lattice (DKL), which possesses the characteristics of an intri…
Design monolayer iodinenes based on halogen bond and tiling theory
Kejun Yu, Botao Fu, Runwu Zhang +5
Xenes, two-dimensional (2D) monolayers composed of a single element, with graphene as a typical representative, have attracted widespread attention. Most of the previous Xenes, X f…
Flat-band and multi-dimensional fermions in Pb10(PO4)6O4
Botao Fu, Qin He, Xiao-Ping Li
Employing a combination of first-principles calculations and low-energy effective models, we present a comprehensive investigation on the electronic structure of Pb(PO…
