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…
Orbital and Spin Character of Doped Carriers in Infinite-Layer Nickelates
M. Rossi, H. Lu, A. Nag +13
The recent discovery of superconductivity in NdSrNiO has drawn significant attention in the field. A key open question regards the evolution of the electronic str…
Unraveling the orbital physics in a canonical orbital system KCuF
Jiemin Li, Lei Xu, Mirian Garcia-Fernandez +9
We explore the existence of the collective orbital excitations, orbitons, in the canonical orbital system KCuF. Using the Cu -edge resonant inelastic X-ray scattering we s…
Evolution of spin excitations from bulk to monolayer FeSe
J. Pelliciari, S. Karakuzu, Q. Song +17
The discovery of enhanced superconductivity (SC) in FeSe films grown on SrTiO3 (FeSe/STO) has revitalized the field of Fe-based superconductors. In the ultrathin limit, the superco…
Dynamical spin susceptibility in La2CuO4 studied by resonant inelastic x-ray scattering

Resonant inelastic X-ray scattering (RIXS) is a powerful probe of elementary excitations in solids. It is now widely applied to study magnetic excitations. However, its complex cro…
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…
Spectroscopic Evidence for Charge Order Melting via Quantum Fluctuations in a Cuprate
W. S. Lee, K. J. Zhou, M. Hepting +14
Copper-oxide high TC superconductors possess a number of exotic orders co-existing with or proximal to superconductivity, whose quantum fluctuations may account for the unusual beh…
Detection of Acoustic Plasmons in Hole-Doped Lanthanum and Bismuth Cuprate Superconductors Using Resonant Inelastic X-Ray Scattering
Abhishek Nag, M. Zhu, Matias Bejas +11
High Tc superconductors show a rich variety of phases associated with their charge degrees of freedom. Valence charges can give rise to charge ordering or acoustic plasmons in thes…
Multi-orbital charge density wave excitations and concomitant phonon anomalies in BiSrLaCuO
Jiemin Li, Abhishek Nag, Jonathan Pelliciari +9
Charge density waves (CDWs) are ubiquitous in under-doped cuprate superconductors. As a modulation of the valence electron density, CDWs in hole-doped cuprates possess both Cu-3d a…
