Stabilization of three-dimensional charge order through interplanar orbital hybridization in PrYBaCuO
Alejandro Ruiz, Brandon Gunn, Yi Lu +13
The shape of 3-orbitals often governs the electronic and magnetic properties of correlated transition metal oxides. In the superconducting cuprates, the planar confinement of th…
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…
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…
Non-perturbative series expansion of Green's functions: The Anatomy of Resonant Inelastic X-Ray Scattering in Doped Hubbard Model
Yi Lu, Maurits W. Haverkort
We present a non-perturbative, divergence-free series expansion of Green's functions using effective operators. The method is especially suited for computing correlators of complex…
