Itinerant Nature of Spin-Density-Wave Order in Ruddlesden-Popper Nickelates
Jiong Mei, Tianyang Xie, Kun Jiang
The nature of magnetism in layered Ruddlesden-Popper nickelates remains a central open question, particularly in light of recent observations of spin-wave-like magnetic excitations…
Frustration from Localized Zhang-Rice States: A Unified Theory of Doping-Driven Magnetic Transitions in Cuprates
Xiaodong Wang, Ping Xu, Jiong Mei +5
The microscopic mechanism by which doped holes disrupt the antiferromagnetic order is one of the fundamental questions in cuprates. In this work, we propose a unified microscopic t…
Magnetic electron-hole asymmetry in cuprates: a computational revisit
Jiong Mei, Shao-Hang Shi, Ping Xu +5
In this work, we revisit the electron-hole asymmetry of antiferromagnetism in cuprates by studying the three-band Emery model. Using parameters relevant to LaCuO, we benchm…
Interband-Pairing-Boosted Supercurrent Diode Effect in Multiband Superconductors
Jiong Mei, Shengshan Qin, Jiangping Hu
We unveil a mechanism that enables a robust supercurrent diode effect in Josephson junctions based on multiband superconductors. We predict that interband pairing can significantly…
