Beyond the conventional Emery model: crucial role of long-range hopping for cuprate superconductivity
Eric Jacob, M. O. Malcolms, Viktor Christiansson +6
The Emery model is the quintessential model for cuprate superconductors. In his eponymous paper, Emery only considered the next-nearest-neighbor oxygen-copper hopping. Later, also…
Rise and Fall of the Pseudogap in the Emery model: Insights for Cuprates
M. O. Malcolms, Henri Menke, Yi-Ting Tseng +4
The pseudogap in high-temperature superconducting cuprates is an exotic state of matter, displaying emerging Fermi arcs and a momentum-selective suppression of states upon cooling.…
Charge transfer energy in iridates: a hard x-ray photoelectron spectroscopy study
D. Takegami, D. Kasinathan, K. K. Wolff +20
We have investigated the electronic structure of iridates in the double perovskite crystal structure containing either Ir or Ir using hard x-ray photoelectron spectro…
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…
Exploring small energy scales with x-ray absorption and dichroism
C. Praetorius, M. Zinner, P. Hansmann +2
Soft x-ray linear and circular dichroism (XLD, XMCD) experiments at the Ce M edges are being used to determine the energy scales characterizing the Ce degrees of freed…
Mechanism of charge transfer/disproportionation in LnCu3Fe4O12 (Ln: Lanthanides)
N. Rezaei, P. Hansmann, M. S. Bahramy +1
The Fe-Cu intersite charge transfer and Fe charge disproportionation are interesting phenomena observed in some LnCu3Fe4O12 (Ln: Lanthanides) compounds containing light and heavy L…
