Light-induced ultrafast dynamics of spin crossovers in LaCoO3
Yu. S. Orlov, S. V. Nikolaev, S. G. Ovchinnikov
Ultrafast quantum dynamics relaxation of a photoexcited state in a strongly correlated spin crossover system LaCoO3 under a sudden perturbation is considered with the density matri…
Phonon-assisted insulator-metal transitions in correlated systems driven by doping
E. I. Shneyder, M. V. Zotova, S. V. Nikolaev +1
We consider how electron-phonon interaction influences the insulator-metal transitions driven by doping in the strongly correlated system. Using the polaronic version of the genera…
Ultrafast dynamics of light-induced spin crossovers under high pressure
Yu. S. Orlov, S. V. Nikolaev, A. I. Nesterov +1
Within the multielectron model of magnetic insulator with spin crossover under high pressure we have studied the mean field phase diagrams in pressure temperature plane and dynamic…
Polaron transformations in the realistic model of the strongly correlated electron system
E. I. Shneyder, S. V. Nikolaev, M. V. Zotova +2
Electron-phonon coupling, diagonal in a real space formulation, leads to polaron paradigm of smoothly varying properties. However, fundamental changes, namely the singular behavior…
Doping and temperature evolution of pseudogap and spin-spin correlations in the two-dimensional Hubbard model
Valerii Kuz'min, Maxim Visotin, Sergey Nikolaev +1
Cluster perturbation theory is applied to the two-dimensional Hubbard model to obtain doping and temperature dependent electronic spectral function with a…
Effect of short-range correlations on spectral properties of doped Mott insulators
V. I. Kuz'min, S. V. Nikolaev, S. G. Ovchinnikov
In the framework of cluster perturbation theory for the 2D Hubbard and Hubbard-Holstein models at low hole doping we have studied the effect of local and short-range correlations i…
