Photo-induced charge-transfer renormalization in NiO
Tobias Lojewski, Denis Golez, Katharina Ollefs +21
Photo-doped states in strongly correlated charge transfer insulators are characterized by - and - interactions and the resulting intertwined dynamics of charge excitati…
The interplay of local electron correlations and ultrafast spin dynamics in fcc Ni
Tobias Lojewski, Mohamed F. Elhanoty, Loïc Le Guyader +48
The complex electronic structure of metallic ferromagnets is determined by a balance between exchange interaction, electron hopping leading to band formation, and local Coulomb rep…
Charge disproportionation and nano phase separation in SrNiO
H. Guo, Z. W. Li, C. F. Chang +16
We have successfully grown centimeter-sized layered SrNiO single crystals under high oxygen pressures of 120 bar by the floating zone technique. This enabled us to perform n…
Direct observation of multi-spinon excitations outside of the two-spinon continuum in the antiferromagnetic spin chain cuprate Sr2CuO3
J. Schlappa, U. Kumar, K. J. Zhou +8
One-dimensional (1D) magnetic insulators have attracted significant interest as a platform for studying emergent phenomena such as quasiparticle fractionalization and quantum criti…
Orbital superexchange and crystal field simultaneously at play in YVO3: resonant inelastic x-ray scattering at the V L edge and the O K edge
E. Benckiser, L. Fels, G. Ghiringhelli +11
We report on the observation of orbital excitations in YVO3 by means of resonant inelastic x-ray scattering (RIXS) at energies across the vanadium L3 and oxygen K absorption edges.…
Spin-Orbital Separation in the quasi 1D Mott-insulator Sr2CuO3
J. Schlappa, K. Wohlfeld, K. J. Zhou +13
As an elementary particle the electron carries spin \hbar/2 and charge e. When binding to the atomic nucleus it also acquires an angular momentum quantum number corresponding to th…
