Non-Hermitian bulk-boundary correspondence and auxiliary generalized Brillouin zone theory
Zhesen Yang, Kai Zhang, Chen Fang +1
We provide a systematic and self-consistent method to calculate the generalized Brillouin Zone (GBZ) analytically in one dimensional non-Hermitian systems, which helps us to unders…
Fermion doubling theorems in 2D non-Hermitian systems for Fermi points and exceptional points
Zhesen Yang, A. P. Schnyder, Jiangping Hu +1
The fermion doubling theorem plays a pivotal role in Hermitian topological materials. It states, for example, that Weyl points must come in pairs in three-dimensional semimetals. H…
Evidence for an Additional Symmetry Breaking from Direct Observation of Band Splitting in the Nematic State of FeSe Superconductor
Cong Li, Xianxin Wu, Le Wang +26
The iron-based superconductor FeSe has attracted much recent attention because of its simple crystal structure, distinct electronic structure and rich physics exhibited by itself a…
A substantial hybridization between correlated Ni-d orbital and itinerant electrons in infinite-layer nickelates
Yuhao Gu, Sichen Zhu, Xiaoxuan Wang +2
The discovery of unconventional superconductivity in hole doped NdNiO2, similar to CaCuO2, has received enormous attention. However, different from CaCuO2, RNiO2 (R = Nd, La) has i…
A New Quasi One-Dimensional Compound Ba3TiTe5 and Superconductivity Induced by Pressure
Jun Zhang, Yating Jia, Xiancheng Wang +14
We report systematical studies of a new quasi-one-dimensional (1D) compound Ba3TiTe5 and the high-pressure induced superconductivity therein. Ba3TiTe5 was synthesized at high press…
Unconventional High Temperature Superconductivity in Cubic Zinc-blende Transition Metal Compounds
Qiang Zhang, Kun Jiang, Yuhao Gu +1
We consider possible high temperature superconductivity (high-T) in transition metal compounds with a cubic zinc-blende lattice structure. When the electron filling configurati…
