Damping of spinful excitons in LaCoO by thermal fluctuations: Theory and experiment
Atsushi Hariki, Ru-Pan Wang, Andrii Sotnikov +7
We present Co -edge resonant inelastic x-ray scattering (RIXS) of bulk LaCoO across the thermally-induced spin-state crossover around 100~K. Owing to a high energy resolut…

Excitonic dispersion of the intermediate-spin state in LaCoO revealed by resonant inelastic X-ray scattering
Ru-Pan Wang, Atsushi Hariki, Andrii Sotnikov +9
More than 50 years ago the electron-hole attraction was proposed to drive narrow gap semiconductors or semimetals to a new phase, the excitonic insulator. The experimental proof of…

Coulomb correlations intertwined with spin and orbital excitations in LaCoO
K. Tomiyasu, J. Okamoto, H. Y. Huang +11
We carried out temperature-dependent (20 - 550 K) measurements of resonant inelastic X-ray scattering on LaCoO to investigate the evolution of its electronic structure across t…
