Dissecting superconductivity in the Ruddlesden-Popper nickelates: The role of electron correlation and interlayer magnetic exchange
Xiaoyang Chen, Zezhong Li, Mei Xie +9
The discovery of superconductivity in the Ruddlesden-Popper (RP) nickelates has opened a new chapter in the search for high superconducting transition temperatures ()…
Orbital Separation of Charge Order and Superconductivity in LaSrCuO

We report a combined x-ray absorption (XAS) and oxygen -edge resonant inelastic x-ray scattering (RIXS) study of charge order in underdoped LaSrCuO () u…
Impact of Electron Correlations on Infinite-Layer Cuprates and Nickelates
Xunyang Hong, Yuetong Wu, Ying Chan +18
Optimization of unconventional superconductivity involves a balance of interaction strengths. Precise determination of correlation strength across different material families is th…
Unveiling the nature of collective charge excitations in a cuprate superconductor
Xunyang Hong, Yujie Yan, Leonardo Martinelli +33
Emergent symmetry breakings in condensed matter systems are often intimately linked to collective excitations. For example, the intertwined spin-charge stripe order in cuprate supe…
