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
I. BiaÅo, O. Gerguri, L. Martinelli +12
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 +20
Optimization of unconventional superconductivity involves a balance of interaction strengths. Precise determination of correlation strength across different material families is th…
Observation of collective charge excitations in a cuprate superconductor
Xunyang Hong, Yujie Yan, L. Martinelli +12
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…
Decoupling of Static and Dynamic Charge Correlations revealed by Uniaxial Strain in a Cuprate Superconductor
L. Martinelli, I. BiaÅo, X. Hong +17
We use uniaxial strain in combination with ultra-high-resolution Resonant Inelastic X-ray Scattering (RIXS) at the oxygen K- and copper L3-edges to study the excitations stemming f…
Emergence of interfacial magnetism in strongly-correlated nickelate-titanate superlattices
Teguh Citra Asmara, Robert J. Green, Andreas Suter +21
Strongly-correlated transition-metal oxides are widely known for their various exotic phenomena. This is exemplified by rare-earth nickelates such as LaNiO, which possess int…
