Suppression of p-Wave Altermagnetism by Localized 4f Electrons in CeNiAsO
Jiuxiang Zhang, Yueyang Sun, Honglin Zhou +32
Altermagnetism, characterized by momentum-dependent spin splitting and zero net magnetization, has so far been explored mainly in weakly or moderately correlated d-electron systems…
Coexistence of High Temperature Superconductivity and Antiferromagnetic Order in a Cuprate with Multiple Hole Fermi Pockets
Xiangyu Luo, Yinghao Li, Hao Chen +23
The intricate relationship between high temperature superconductivity and antiferromagnetic order in cuprates, and the fundamental origin of electron pairing remain open questions.…
Persistent Fermi Pockets and Robust Electron Pairing in Lightly Doped CuO Planes of Cuprate Superconductors
Hao Chen, Jumin Shi, Yinghao Li +23
High temperature superconductivity in cuprate superconductors is generally considered to be generated from doping the Mott insulators. The fundamental nature of the doped parent co…
Mott-Derived Local Moments and Kondo Hybridization in a d-electron Kagome lattice
Xing Zhang, Xintong Li, Boqin Song +25
Unlike canonical Kondo lattices in f-electron systems, where localized f orbitalsnaturally provide local moments, d-electron Kondo lattices require a distinct mechanism for local-m…
Expansion of Momentum Space and Full 2 Solid Angle Photoelectron Collection in Laser-Based Angle-Resolved Photoemission Spectroscopy by Applying Sample Bias
Taimin Miao, Yu Xu, Bo Liang +18
Angle-resolved photoemission spectroscopy (ARPES) directly probes the energy and momentum of electrons in quantum materials, but conventional setups capture only a small fraction o…
Interface-Enhanced Superconductivity in Ultrathin TiN Proximitized by Topological Insulators
Renjie Xie, Bowen Hao, Min Ge +11
High-quality topological insulator-superconductor (TI-SC) heterostructure with an atomically sharp and well-controlled interface is crucial for realizing topological superconductiv…
