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…
Sign-reversible valley-dependent Berry phase effects in 2D valley-half-semiconductors
Xiaodong Zhou, Run-Wu Zhang, Zeying Zhang +3
Manipulating valley-dependent Berry phase effects provides remarkable opportunities for both fundamental research and practical applications. Here, by referring to effective model…
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…
Magnetic higher-order nodal lines
Zeying Zhang, Zhi-Ming Yu, Shengyuan A. Yang
Nodal lines, as one-dimensional band degeneracies in momentum space, usually feature a linear energy splitting. Here, we propose the concept of magnetic higher-order nodal lines, w…
SpaceGroupIrep: A package for irreducible representations of space group
Gui-Bin Liu, Miao Chu, Zeying Zhang +2
We have developed a Mathematica program package SpaceGroupIrep which is a database and tool set for irreducible representations (IRs) of space group in BC convention, i.e. the conv…
