Evolution of orbital excitations from insulating to superconducting MgTiO films
Qizhi Li, Abhishek Nag, Xiquan Zheng +6
Spinel oxides are well-known functional materials but rarely show superconductivity. Recently, emergent superconductivity was discovered in MgTiO, which is attributed to th…
A Broken Translational Symmetry State in an Infinite-Layer Nickelate
Matteo Rossi, Motoki Osada, Jaewon Choi +17
A defining signature of strongly correlated electronic systems is the existence of competing phases with similar ground state energies, resulting in a rich phase diagram. While in…
Charge density waves in infinite-layer NdNiO nickelates
Charles C. Tam, Jaewon Choi, Xiang Ding +7
In materials science, much effort has been devoted to reproduce superconductivity in chemical compositions analogous to cuprate superconductors since their discovery over thirty ye…
Doping-dependence of the electron-phonon coupling in two families of bilayer superconducting cuprates
Yingying Peng, Leonardo Martinelli, Qizhi Li +21
While electron-phonon coupling (EPC) is crucial for Cooper pairing in conventional superconductors, its role in high- superconducting cuprates is debated. Using resonant inela…
Magnetic excitations in infinite-layer nickelates
H. Lu, M. Rossi, A. Nag +14
The discovery of superconductivity in infinite-layer nickelates brings us tantalizingly close to a new material class that mirrors the cuprate superconductors. Here, we report on m…
Charge Transfer and excitations in AgF
Nimrod Bachar, Kacper Koteras, Jakub Gawraczynski +11
Charge transfer (CT) insulators are the parent phase of a large group of today's unconventional high-temperature superconductors. Here we study experimentally and theoretically the…
Charge Order Lock-in by Electron-Phonon Coupling in LaEuSrCuO
Qisi Wang, K. von Arx, M. Horio +11
We report an ultrahigh resolution resonant inelastic x-ray scattering (RIXS) study of the in-plane bond-stretching phonon mode in stripe-ordered cuprate LaEuSr$_{…
Paramagnons and high-temperature superconductivity in mercury-based cuprates
Lichen Wang, Guanhong He, Zichen Yang +8
We present a comparative study of magnetic excitations in the first two Ruddlesden-Popper members of the Hg-family of high-temperature superconducting cuprates, which are chemicall…
Strong Superexchange in a Nickelate Revealed by Resonant Inelastic X-Ray Scattering
J. Q. Lin, P. Villar Arribi, G. Fabbris +20
The discovery of superconductivity in a nickelate has inspired disparate theoretical perspectives regarding the essential physics of this class of materials. A key issue…
