The effect of different in-chain impurities on the magnetic properties of the spin chain compound SrCuO probed by NMR
Yannic Utz, Franziska Hammerath, Roberto Kraus +14
The S=1/2 Heisenberg spin chain compound SrCuO2 doped with different amounts of nickel (Ni), palladium (Pd), zinc (Zn) and cobalt (Co) has been studied by means of Cu nuclear magne…
Orbital breathing effects in the computation of x-ray d-ion spectra in solids by ab initio wave-function-based methods
Nikolay A. Bogdanov, Valentina Bisogni, Roberto Kraus +8
In existing theoretical approaches to core-level excitations of transition-metal ions in solids relaxation and polarization effects due to the inner core hole are often ignored or…
Probing inter- and intrachain Zhang-Rice excitons in LiCuO and determining their binding energy
Claude Monney, Valentina Bisogni, Ke-Jin Zhou +8
Cuprate materials, like those hosting high temperature superconductivity, represent a famous class of materials where the correlations between the strongly entangled charges and sp…
Electron-lattice interactions strongly renormalize the charge transfer energy in the spin-chain cuprate LiCuO
Steve Johnston, Claude Monney, Valentina Bisogni +9
Strongly correlated insulators are broadly divided into two classes: Mott-Hubbard insulators, where the insulating gap is driven by the Coulomb repulsion on the transition-meta…
Orbital control of effective dimensionality: from spin-orbital fractionalization to confinement in the anisotropic ladder system CaCu2O3
Valentina Bisogni, Krzysztof Wohlfeld, Satoshi Nishimoto +11
Fractionalization of an electronic quasiparticle into spin, charge and orbital parts is a fundamental and characteristic property of interacting electrons in one dimension. However…
Femtosecond dynamics of magnetic excitations from resonant inelastic x-ray scattering in CaCu2O3
Valentina Bisogni, Stefanos Kourtis, Claude Monney +10
Taking spinon excitations in the quantum antiferromagnet CaCu2O3 as an example, we demonstrate that femtosecond dynamics of magnetic excitations can be probed by direct resonant in…
