Layer-Asymmetry-Induced Topological Superconductivity in High-T Bilayer Nickelates
Zhongyi Zhang, Congcong Le, Hoi Chun Po +3
The recent discovery of high-T superconductivity in bilayer nickelates has highlighted the crucial role of interlayer coupling and motivated proposals for dominant interlayer p…
Selective suppression of electronic orders via interlayer coupling in superconducting bilayer nickelate thin films
Ziao Han, Lifen Xiang, Tianren Wang +11
The discovery of spin-density-wave (SDW) order in bilayer nickelates has intensified interest in its interplay with superconductivity. Unlike cuprates, where doping rapidly suppres…
Different reconstruction pathways toward superconductivity in TaRhTe4 and TaIrTe4 Weyl semimetals
Jinyu Zhao, Yang Fu, Congcong Le +9
Pressure can drive Weyl semimetals toward superconductivity through qualitatively distinct reconstructions of their lattices and normal-state electronic structures. Here, we report…
Mode-selective phonon effects on magnetism and superconductivity in trilayer nickelates
