Design monolayer iodinenes based on halogen bond and tiling theory
Kejun Yu, Botao Fu, Runwu Zhang +5
Xenes, two-dimensional (2D) monolayers composed of a single element, with graphene as a typical representative, have attracted widespread attention. Most of the previous Xenes, X f…
Design of Antiferromagnetic Second-order Band Topology with Rotation Topological Invariants in Two Dimensions
Fangyang Zhan, Zheng Qin, Dong-Hui Xu +3
The existence of fractionally quantized topological corner states serves as a key indicator for two-dimensional second-order topological insulators (SOTIs), yet has not been experi…
Realization of a two-dimensional checkerboard lattice in monolayer CuN
Xuegao Hu, Run-Wu Zhang, Da-Shuai Ma +10
Two-dimensional checkerboard lattice, the simplest line-graph lattice, has been intensively studied as a toy model, while material design and synthesis remain elusive. Here, we rep…
Optical bulk-boundary dichotomy in a quantum spin Hall insulator
Junfeng Han, Pengcheng Mao, Hailong Chen +17
The bulk-boundary correspondence is a key concept in topological quantum materials. For instance, a quantum spin Hall insulator features a bulk insulating gap with gapless helical…
2D Ladder polyborane: an ideal Dirac semimetal with a multi-feld-tunable band gap
Botao Fu, Run-Wu Zhang, Xiaotong Fan +3
Hydrogen, a simple and magic element, has attracted increasing attention for its effective incorporation within solids and powerful manipulation of electronic states. Here, we show…
Strain-driven phonon topological phase transition impedes thermal transport in titanium monoxide
Xin Jin, Da-shuai Ma, Peng Yu +4
Topological phonon states in crystalline materials have attracted significant research interests due to their importance for fundamental physical phenomena, yet their implication o…
Hybrid Nodal-chain Semimetal State in MgCaN2
Hongbo Wu, Da-Shuai Ma, Botao Fu
The distinct over-tilting of band crossings in topological semimetal generates the type-I and typeII classification of Dirac/Weyl and nodal-line fermions, accompanied by the exotic…
