Quantum Geometry in the NbSe Family I: Obstructed Compact Wannier Function and New Perturbation Theory
Jiabin Yu, Yi Jiang, Yuanfeng Xu +8
We revisit the electronic structure and band topology of monolayer 1H-NbSe, which hosts both superconductivity and charge density wave, and its related compounds 1H-MoS, Nb…

Probing the Quantized Berry Phases in 1H-NbSe Using Scanning Tunneling Microscopy
Dumitru CÄlugÄru, Yi Jiang, Haojie Guo +7
Topologically trivial insulators are classified into two primary categories: unobstructed and obstructed atomic insulators. While both types can be described by exponentially local…

Layer thickness and substrate effects on superconductivity in epitaxial FeSe films on BLG/SiC(0001)
Yongsong Wang, Haojie Guo, Ane Etxebarria +3
The layered nature and simple structure of FeSe reveal this iron-based superconductor as a unique building block for the design of artificial heterostructure materials. While super…
