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…
Electronic Origin of High Temperature Superconductivity in Single-Layer FeSe Superconductor
Defa Liu, Wenhao Zhang, Daixiang Mou +21
The latest discovery of high temperature superconductivity signature in single-layer FeSe is significant because it is possible to break the superconducting critical temperature ce…
Competing energy scales in topological superconducting heterostructures
Yunyi Zang, Felix Küster, Jibo Zhang +6
Artificially engineered topological superconductivity has emerged as a viable route to create Majorana modes, exotic quasiparticles which have raised great expectations for storing…
