Real topological phonons in 3D carbon allotropes
Xiaotian Wang, Jingbo Bai, Jianhua Wang +6
There has been a significant focus on real topological systems that enjoy space-time inversion symmetry (PT ) and lack spin-orbit coupling. While the theoretical classification of…
3D carbon allotropes: Topological quantum materials with obstructed atomic insulating phases, multiple bulk-boundary correspondences, and real topology
Jianhua Wang, Ting-Ting Zhang, Qianwen Zhang +6
The study of topological phases with unconventional bulk-boundary correspondences and nontrivial real Chern number has garnered significant attention in the topological states of m…
Genuine Dirac half-metal: A 2D d0-type ferromagnet Mg4N4
Jialin Gong, Guangqian Ding, Chengwu Xie +4
When the spin-orbit coupling (SOC) is absent, almost all the proposed half-metals with the twofold degenerate nodal points at the K (or K') in two-dimensional (2D) materials are mi…
Accurate recipe for predicting valley Linear Weyl phonons in two dimensions
Mingmin Zhong, Haibo Liu, Jianhua Wang +5
The discovery of topological quantum states in two-dimensional (2D) systems is one of the most promising advancements in condensed matter physics. Linear Weyl point (LWP) phonons h…
Three-nodal surface phonons in solid-state materials: Theory and material realization
C. W. Xie, H. K. Yuan, Y. Liu +2
This year, Liu \textit{et al}. [Phys. Rev. B \textbf{104}, L041405 (2021)] proposed a new class of topological phonons (TPs; i.e., one-nodal surface (NS) phonons), which provides a…
