Encyclopedia of emergent particles in type-IV magnetic space groups
Zeying Zhang, Gui-Bin Liu, Zhi-Ming Yu +2
The research on emergent particles in condensed matters has been attracting tremendous interest, and recently it is extended to magnetic systems. Here, we study the emergent partic…
Systematic investigation of emergent particles in type-III magnetic space groups
Gui-Bin Liu, Zeying Zhang, Zhi-Ming Yu +2
In three-dimensional (3D) crystals, emergent particles arise when two or multiple bands contact and form degeneracy (band crossing) in the Brillouin zone. Recently a complete class…
-symmetric higher-order topological crystalline insulators in atomically thin transition-metal dichalcogenides
Shifeng Qian, Gui-bin Liu, Cheng-Cheng Liu +1
Based on first-principles calculations and symmetry analysis, we predict atomically thin ( layers) 2H group-VIB TMDs ( = Mo, W; = S, Se, Te) are large-gap higher…
MagneticTB: A package for tight-binding model of magnetic and non-magnetic materials
Zeying Zhang, Zhi-Ming Yu, Gui-Bin Liu +1
We present a Mathematica program package MagneticTB, which can generate the tight-binding model for arbitrary magnetic space group. The only input parameters in MagneticTB are the…
Encyclopedia of emergent particles in three-dimensional crystals
Zhi-Ming Yu, Zeying Zhang, Gui-Bin Liu +5
The past decade has witnessed a surge of interest in exploring emergent particles in condensed matter systems. Novel particles, emerged as excitations around exotic band degeneracy…
