Topotactic hydrogen in nickelate superconductors and akin infinite-layer oxides ABO2
Liang Si, Wen Xiao, Josef Kaufmann +4
Superconducting nickelates appear to be difficult to synthesize. Since the chemical reduction of ABO3 (A: rare earth; B transition metal) with CaH2 may result in both, ABO2 and ABO…
Natural-Orbital Impurity Solver and Projection Approach for Green's Function
Y. Lu, X. Cao, P. Hansmann +1
We extend a previously proposed rotation and truncation scheme to optimize quantum Anderson impurity calculations with exact diagonalization [PRB 90, 085102 (2014)] to density-matr…
Control of dopant crystallinity in electrochemically treated cuprate thin films
Alex Frano, Martin Bluschke, Zhijun Xu +16
We present a methodology based on \textit{ex-situ} (post-growth) electrochemistry to control the oxygen concentration in thin films of the superconducting oxide LaCuO g…
Resonant inelastic x-ray scattering study of bond order and spin excitations in nickelate thin-film structures
K. Fürsich, Y. Lu, D. Betto +13
We used high-resolution resonant inelastic x-ray scattering (RIXS) at the Ni edge to simultaneously investigate high-energy interband transitions characteristic of Ni-O bond…
