Plasmon dispersion in bilayer cuprate superconductors
M. Bejas, V. Zimmermann, D. Betto +11
The essential building blocks of cuprate superconductors are two-dimensional CuO sheets interspersed with charge reservoir layers. In bilayer cuprates, two closely spaced CuO$_…
Single crystal synthesis, structure, and magnetism of PbCu(PO)O
P. Puphal, M. Y. P. Akbar, M. Hepting +4
The recent claim of superconductivity above room temperature in PbCu(PO)O with 0.9 < < 1 (referred to as LK-99) has sparked considerable interest. To minim…
Evolution of plasmon excitations across the phase diagram of the cuprate superconductor LaSrCuO
M. Hepting, T. D. Boyko, V. Zimmermann +19
We use resonant inelastic x-ray scattering (RIXS) at the O - and Cu -edges to investigate the doping- and temperature dependence of low-energy plasmon excitations in La$_{2-x…
Topotactic transformation of single-crystals: from perovskite to infinite-layer nickelates
Pascal Puphal, Yu-Mi Wu, Katrin Fürsich +9
Topotactic transformations between related crystal structures are a powerful emerging route for the synthesis of novel quantum materials. Whereas most such "soft chemistry" experim…
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…
Three dimensional collective charge excitations in electron-doped cuprate superconductors
M. Hepting, L. Chaix, E. W. Huang +17
High temperature cuprate superconductors consist of stacked CuO2 planes, with primarily two dimensional electronic band structures and magnetic excitations, while superconducting c…
