Electronic structure of the CuO monolayer in the paramagnetic phase considering the Coulomb interactions
I. A. Makarov, A. A. Slobodchikov, I. A. Nekrasov +4
The electronic structure of the CuO monolayer is investigated taking into account the intra- and interatomic Coulomb interactions on copper and oxygen atoms. Local Coulomb interact…
Photoinduced Magnetic Transitions and Excitonic Order Enhancement in Spin Crossover Strongly Correlated Electron Systems

Magnetism in spin crossover systems: short-range order and effects beyond the Heisenberg model
V. I. Kuz'min, Yu. S. Orlov, A. E. Zarubin +2
To study non-Heisenberg effects in the vicinity of spin crossover in strongly correlated electron systems we derive an effective low-energy Hamiltonian for the two-band Kanamori mo…
Cooperative Phenomena in Spin Crossover Systems
Alexander I. Nesterov, Yuri S. Orlov, Sergey G. Ovchinnikov +1
Within the framework of a realistic multi-band p-d-model, we derived an effective Hamiltonian to describe the exchange interaction effects near the spin crossover in magnetic Mott-…
Temperature induced in-gap states in the band structure and the insulator-metal transition in LaCoO3
S. Ovchinnikov, Yu. Orlov, I. Nekrasov +1
For many years a spin-state transition at and insulator - metal transition (IMT) at in LaCoO remains a mystery. Small low-spin - high…
