Inventory of high-quality flat-band van der Waals materials
Jingyi Duan, Da-Shuai Ma, Run-Wu Zhang +5
More is left to do in the field of flat bands besides proposing theoretical models. One unexplored area is the flat bands featured in the van der Waals (vdW) materials. Exploring m…
A phonon irreducible representations calculator
Zeying Zhang, Zhi-Ming Yu, Gui-Bin Liu +1
The irreducible representation of band structure is important for physical properties. Based on phonopy and recently developed SpaceGroupIrep package, we developed a package Phonon…
Multiple magnetism controlled topological states in EuAgAs
Yahui Jin, Xu-Tao Zeng, Xiaolong Feng +6
The interplay between magnetism and band topology is a focus of current research on magnetic topological systems. Based on first-principle calculations and symmetry analysis, we re…
Charge-4 Weyl point: Minimum lattice model and chirality-dependent properties
Chaoxi Cui, Xiao-Ping Li, Da-Shuai Ma +2
Topological Weyl semimetals have been attracting broad interest. Recently, a new type of Weyl point with topological charge of , termed as charge-4 Weyl point (C-4 WP), was prop…
Coexistence of zero-, one- and two-dimensional degeneracy in tetragonal SnO phonons
Jianhua Wang, Hongkuan Yuan, Minquan Kuang +4
Based on the dimension of degeneracy, topological electronic systems can roughly be divided into three parts: nodal point, line and surface materials corresponding to zero-, one- a…
Triply-degenerate point in three-dimensional spinless systems
Xiaolong Feng, Weikang Wu, Zhi-Ming Yu +1
We study the possibility of triply-degenerate points (TPs) that can be stabilized in spinless crystalline systems. Based on an exhaustive search over all 230 space groups, we find…
