Unconventional phonon spectra and obstructed edge phonon modes
Ruihan Zhang, Haohao Sheng, Junze Deng +3
Based on the elementary band representations (EBR), some topologically trivial materials are classified as unconventional ones (obstructed atomic limit), where the EBR decompositio…
Two elementary band representation model, Fermi surface nesting, and surface topological superconductivity in VSb ()
Junze Deng, Ruihan Zhang, Yue Xie +2
The recently discovered vanadium-based Kagome metals VSb () are of great interest with the interplay of charge density wave (CDW) order, band t…
Large shift current, Zak phase and unconventional nature in Se and Te
Ruihan Zhang, Junze Deng, Yan Sun +3
Recently, unconventional materials (or obstructed atomic insulators) have attracted much attention owing to the unconventional feature of mismatch between Wannier centers and atomi…
Large spin Hall conductivity and excellent hydrogen evolution reaction activity in unconventional PtTe1.75 monolayer
Dexi Shao, Junze Deng, Haohao Sheng +6
Two-dimensional (2D) materials have gained lots of attention due to the potential applications. In this work, we propose that based on first-principles calculations, the (2…
Quadrupole topological insulators in Ta2M3Te5 (M= Ni, Pd) monolayers
Zhaopeng Guo, Junze Deng, Yue Xie +1
Higher-order topological insulators have been introduced in the precursory Benalcazar-Bernevig-Hughes quadrupole model, but no electronic compound has been proposed to be a quadrup…
