Ferroelectrically Controlled Chirality Switching of Weyl Quasiparticles
Zeling Li, Yu liu, Le Du +6
Weyl quasiparticles, as gapless low-energy excitations with nontrivial chirality, have garnered extensive interest in recent years. However, archieving effective and reversible con…
Theoretical Design of Mono-Elemental Ferroelectricity with Tunable Spin Textures in Bilayer Tellurium
Jiajun Zhu, Botao Fu, Heyun Zhao +1
2D Ferroelectricity with switchable electric polarization has drawn widespread attention in condensed matter physics due to its crucial applications in non-volatile memory and ferr…
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…
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…
