Relative hybridization textures as local coordinates for band geometry and topology
Caiyuan Ye, Zhong Fang, Hongming Weng +1
The paper introduces a projector-level diagnostic called the relative hybridization coordinate Z, which links global band geometry quantities such as Berry curvature and quantum me…
A Catalogue of Topological Moiré Bands in Twisted Semiconductors
Jiaheng Li, Yan Zhang, Jiaxuan Liu +5
Twisted two-dimensional semiconductors provide a route to flat and topological moiré minibands, but systematic principles for organizing their material dependence have remained un…
A Geometric Design Principle for Topological Phases in Twisted Triangular-Lattice Bilayers
Jiaheng Li, Jiaxuan Liu, Yan Zhang +3
Twisted van der Waals bilayers provide a versatile platform for moiré electronic states, yet a transferable symmetry-based principle for time-reversal-invariant moi…
Symmetry-Indicated Time-Reversal-Doubled Axion Insulators
Yue Xie, Haohao Sheng, Quansheng Wu +4
The axion insulator exhibits a topological magnetoelectric effect characterized by an axion angle , while the time-reversal-doubled axion insulator (T-DAXI) can be viewed as…
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…
Chern-Selective multi-valley Flat Bands in Twisted Mono-Bilayer and Mono-Trilayer MoTe
Ziyue Qi, Hanqi Pi, Yan Zhang +6
The interplay between moiré flat bands originating from different valleys can give rise to a variety of exotic quantum phases. In this work, we investigate the electronic properti…
