Nonthermal melting and density wave instability coupled to the lattice in LaNiO
Chen Zhang, Lixing Chen, Qi-Yi Wu +15
The recent discovery of high-temperature superconductivity in pressurized nickelates has renewed interest in the broken-symmetry states of their ambient-pressure parent phases, whe…
Density-wave order enhances the phonon thermal Hall effect in a trilayer nickelate
Qiaochao Xiang, Enkang Zhang, Xiaokang Li +6
Ruddlesden--Popper nickelates have emerged as a promising platform for high-temperature superconductivity, yet the role of lattice degrees of freedom in their correlated normal sta…
Interlayer electronic coherence links magnetism and superconductivity in Ruddlesden-Popper nickelates
Feiyang Liu, Lixing Chen, Enkang Zhang +2
The extent to which electronic dimensionality influences magnetism and superconductivity in Ruddlesden-Popper (RP) nickelates remains unsettled. Here we report high-precision cryst…
Nature of magnetism in bilayer nickelate La3Ni2O7 single crystals
Lixing Chen, Enkang Zhang, Yiqing Hao +10
The recent discovery of high-temperature superconductivity in pressurized and thin film nickelates has generated intense interest, yet the nature of magnetism in their ambient-pres…
Collective spin excitations in trilayer nickelate LaNiO
Ying Chan, Yuehong Li, Yujie Yan +14
Ruddlesden-Popper (RP) nickelates have recently emerged as a new family of high-temperature superconductors. In bilayer RP nickelates, magnetic excitations with large exchange coup…
On estimating superconducting shielding volume fraction from susceptibility in pressurized Ruddlesden-Popper nickelates: Response to arXiv:2602.19282
Yinghao Zhu, Di Peng, Enkang Zhang +10
In a recent preprint (arXiv:2602.19282) [1], the authors questioned the procedure we used to evaluate the demagnetization-corrected superconducting shielding volume fraction in pre…
