Massive 1D Dirac Line, Solitons and Reversible Manipulation on the Surface of a Prototype Obstructed Atomic Insulator, Silicon

Zhongkai Liu, Peng Deng, Yuanfeng Xu +16

Topologically trivial insulators can be classified into atomic insulators (AIs) and obstructed atomic insulators (OAIs) depending on whether the Wannier charge centers are localize…

Fermi Surface and Band Structure of (Ca,La)FeAs2 Superconductor from Angle-Resolved Photoemission Spectroscopy

Xu Liu, Defa Liu, Lin Zhao +17

The (Ca,R)FeAs2 (R=La,Pr and etc.) superconductors with a signature of superconductivity transition above 40 K possess a new kind of block layers that consist of zig-zag As chains.…

CeCoP: a unique Co-antiferromagnetic topological heavy-fermion system with -protected Kondo effect and nodal-line excitations

Haoyu Hu, Yi Jiang, Defa Liu +5

Based on high-throughput screening and experimental data, we find that CeCoP is unique in heavy-fermion materials: it has a Kondo effect at a high temperature which is none…

Evidence of Electron-Hole Imbalance in WTe2 from High-Resolution Angle-Resolved Photoemission Spectroscopy

Chenlu Wang, Yan Zhang, Jianwei Huang +25

WTe2 has attracted a great deal of attention because it exhibits extremely large and nonsaturating magnetoresistance. The underlying origin of such a giant magnetoresistance is sti…
