Majorana Zero Modes and Topological Nature in Bi2Ta3S6-family Superconductors
Yue Xie, Zhilong Yang, Ruihan Zhang +7
In this work, we report that Bi2Ta3S6-family superconductors exhibit nontrivial band topology. They possess a natural quantum-well structure consisting of alternating stacks of TaS…
Growth and hydrostatic-pressure study of a type-II superconductor BiTaS single crystal
Li Chenglin, Yang Yaling, Yang Zhilong +9
We report the growth and physical properties of single-crystalline BiTaS crystallizing in space group, which comprises alternating Ta-S layers and Bi layers…
Axion insulator, Weyl points, quantum anomalous Hall effect and magnetic topological phase transition in Eu3In2As4
Jingyu Yao, Ruihan Zhang, Sheng Zhang +5
The magnetic topological phases attract much interest, such as the axion insulator, higher-order topology, Weyl semimetals, and the quantum anomalous Hall effect (QAHE). Here, we p…
Excitonic Instability in Ta2Pd3Te5 Monolayer
Jingyu Yao, Haohao Sheng, Ruihan Zhang +7
By systematic theoretical calculations, we have revealed an excitonic insulator (EI) in the Ta2Pd3Te5 monolayer. The bulk Ta2Pd3Te5 is a van der Waals (vdW) layered compound, where…
Superconductivity in unconventional metals
Zhilong Yang, Haohao Sheng, Zhaopeng Guo +5
Based on first-principles calculations, we demonstrate that 1H/2H-phase transition metal dichalcogenides MX2 (M=Nb,Ta; X=S,Se,Te) are unconventional metals, which have an empty-sit…
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…
Magnetic field filtering of the hinge supercurrent in unconventional metal NiTe-based Josephson junctions
Tian Le, Ruihan Zhang, Changcun Li +11
Topological materials with boundary (surface/edge/hinge) states have attracted tremendous research interest. Besides, unconventional (obstructed atomic) materials have recently dra…
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…
