Charge-transfer effect in hard x-ray 1 and 2 photoemission spectra: LDA+DMFT and cluster-model analysis
Mahnaz Ghiasi, Atsushi Hariki, Mathias Winder +6
We study and hard x-ray photoemission spectra (XPS) in a series of late transition metal oxides: FeO (3), FeTiO (3), CoO (3) and NiO (3$d…
Collective Modes in Excitonic Magnets: Dynamical Mean-Field Study
D. Geffroy, J. Kaufmann, A. Hariki +3
We present a dynamical mean-field study of dynamical susceptibilities in two-band Hubbard model. Varying the model parameters we analyze the two-particle excitations in the normal…
Continuum Charge Excitations in High-Valence Transition-Metal Oxides Revealed by Resonant Inelastic X-ray Scattering
Atsushi Hariki, Mathias Winder, Jan Kuneš
We present a theoretical investigation of the origin of Raman-like and fluorescencelike (FL) features of resonant inelastic x-ray scattering (RIXS) spectra. Using a combination of…
Excitonic magnet in external field: complex order parameter and spin currents
D. Geffroy, A. Hariki, J. Kunes
We investigate spin-triplet exciton condensation in the two-orbital Hubbard model close to half filling by means of dynamical mean-field theory. Employing an impurity solver that h…
