The magnon-mediated attraction between two holes doped in a CuO layer
Mirko M. Moeller, Clemens P. J. Adolphs, Mona Berciu
Using a realistic multi-band model for two holes doped into a CuO layer, we devise a method to turn off the magnon-mediated interaction between the holes. This allows us to ver…
Effect of the electron-lattice coupling on the charge and magnetic order in rare-earth nickelates
Stepan Fomichev, Giniyat Khaliullin, Mona Berciu
We investigate the impact of electron-lattice coupling on the stability of various magnetic orders in rare-earth nickelates. We use the Hartree-Fock approximation, at zero temperat…
The critical nature of the Ni spin state in doped NdNiO
Mi Jiang, Mona Berciu, George A. Sawatzky
Superconductivity with was recently found in doped NdNiO. The NiO layers are expected to be Mott insulators so hole doping should produce Ni…
Spectral properties of spin-orbital polarons as a fingerprint of orbital order
Krzysztof Bieniasz, Mona Berciu, Andrzej M. Oleś
Transition metal oxides are a rich group of materials with very interesting physical properties that arise from the interplay of the charge, spin, orbital, and lattice degrees of f…
Relevance of Cu-3d multiplet structure in models of high Tc cuprates
Mi Jiang, Mirko Moeller, Mona Berciu +1
We revisit the problem of the spectra of two holes in a CuO layer, modeled as a Cu-d impurity with full multiplet structure coupled to a full O-2p band as an approximat…
