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…
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…
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…
Extreme Fermi surface smearing in a maximally disordered concentrated solid solution
Hannah C. Robarts, Thomas E. Millichamp, Daniel A. Lagos +13
We show that the Fermi surface can survive the presence of extreme compositional disorder in the equiatomic alloy NiFeCoCr. Our high-resolution…
