Hidden Charge Order in an Iron Oxide Square-Lattice Compound
Jung-Hwa Kim, Darren C. Peets, Manfred Reehuis +14
Since the discovery of charge disproportionation in the FeO square-lattice compound SrFeO by Mössbauer spectroscopy more than fifty years ago, the spatial ordering…
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
H. C. Robarts, M. Garcia-Fernandez, J. Li +5
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…
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…
