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…
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…
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…
Search for resonances decaying into a weak vector boson and a Higgs boson in the fully hadronic final state produced in protonproton collisions at TeV with the ATLAS detector
ATLAS Collaboration
A search for heavy resonances decaying into a or boson and a Higgs boson produced in protonproton collisions at the Large Hadron Collider at TeV is prese…
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…
Crystalline and magnetic structure of Ba2CuO3+δ investigated by x-ray absorption spectroscopy and resonant inelastic x-ray scattering
Roberto Fumagalli, Abhishek Nag, Stefano Agrestini +8
Motivated by the recent synthesis of BaCuO (BCO), a high temperature superconducting cuprate with putative ground state symmetry, we investigated its ele…
