Electron-hole asymmetry in electron systems with orbital degeneracy and correlated hopping
Yu. Skorenkyy, O. Kramar, Yu. Dovhopyaty
Microscopic models of electronic subsystems with orbital degeneracy of energy states and non-diagonal matrix elements of electron interactions (correlated hopping) are considered w…
Mott-Hubbard localization in model of electronic subsystem of doped fullerides
Yuriy Dovhopyaty, Leonid Didukh, Oleksandr Kramar +2
Microscopical model of a doped fulleride electronic subsystem taking into account the triple orbital degeneracy of energy states is considered within the configurational-operator a…
Magnetic field dependence of conductivity and effective mass of carriers in a model of Mott-Hubbard material
L. Didukh, O. Kramar, Yu. Skorenkyy +1
The influence of external magnetic field on a static conductivity of Mott-Hubbard material which is described by model with correlated hopping of electrons has been investigate…
Ground state energy of metallic ferromagnet in a generalized Hubbard model
L. Didukh, O. Kramar, Yu. Skorenkyy
In the present work ferromagnetic ordering in the Hubbard model generalized by taking into account the inter-atomic exchange interaction and correlated hopping in partially filled…
Some Low-Temperature Properties of a Generalized Hubbard Model with Correlated Hopping
L. Didukh, V. Hankevych, Yu. Skorenkyy
In the present paper we study some correlation effects in a generalized Hubbard model with correlated hopping within low-temperature region using a generalized mean-field approxima…
Electron Correlations in Narrow Energy Bands: Ground State Energy and Metal-Insulator Transition
Leonid Didukh, Yuriy Skorenkyy
The electron correlations in narrow energy bands are examined in framework of the Hubbard model. The single-particle Green function and energy spectrum are obtained in paramagnetic…
Metal-insulator transition in a doubly orbitally degenerate model with correlated hopping
L. Didukh, Yu. Skorenkyy, Yu. Dovhopyaty +1
In the present paper we propose a doubly orbitally degenerate narrow-band model with correlated hopping. The peculiarity of the model is taking into account the matrix element of e…
