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…

Theoretical investigation of excitonic magnetism in LaSrCoO
J. Fernández Afonso, A. Sotnikov, J. Kuneš
We use the LDA+U approach to search for possible ordered ground states of LaSrCoO. We find a staggered arrangement of magnetic multipoles to be stable over a broad range of Co…

Competing phases in a model of Pr-based cobaltites
Andrii Sotnikov, Jan Kuneš
Motivated by the physics of Pr-based cobaltites, we study the effect of the external magnetic field in the hole-doped two-band Hubbard model close to instabilities toward the excit…
