Checkerboard-type Zhang-Rice States in Overdoped Cuprate Superconductors
Xiongfang Liu, Kun Han, Yan Peng +13
Cuprate superconductors remain central to condensed matter physics due to their technological relevance and unconventional, incompletely understood electronic behavior. While the c…
Magnetic Ni-N-Ni Centers in N-substituted NiO
Simon Godin, Ilya S. Elfimov, Fengmiao Li +6
To explore how anion substitution modifies the existing magnetism in strongly correlated oxides, we investigate local electronic states and magnetic ordering in nickel oxide (NiO)…
Negative charge transfer energy in correlated compounds
Robert J. Green, George A. Sawatzky
In correlated compounds containing cations in high formal oxidation states (assigned by assuming that anions attain full valence shells), the energy of ligand to cation charge tran…
Heavy anion solvation of polarity fluctuations in Pnictides
G. A. Sawatzky, I. S. Elfimov, J. van den Brink +1
Once again the condensed matter world has been surprised by the discovery of yet another class of high temperature superconductors. The discovery of iron-pnictide (FeAs) and chalco…
Physics of cuprates with the two-band Hubbard model - The validity of the one-band Hubbard model
A. Macridin, Th. Maier, M. Jarrell +1
We calculate the properties of the two-band Hubbard model using the Dynamical Cluster Approximation. The phase diagram resembles the generic phase diagram of the cuprates, showing…
Temperature dependent changes of the Mn 3d and 4p bands near T in Colossal Magnetoresistance systems: a XANES study of LaCaMnO
F. Bridges, C. H. Booth, G. H. Kwei +2
We report high-resolution X-ray Absorption Near Edge Structure (XANES) measurements at the Mn K-edge as a function of temperature, for LaCaMnO samples, with a focus…
