Origin of the electron disproportionation in the metallic sodium cobaltates
Y. V. Lysogorskiy, S. A. Krivenko, I. R. Mukhamedshin +3
Recently the unusual metallic state with a substantially non-uniform distribution of a charge and mag\-ne\-tic density in CoO planes was found experimentally in the NaCoO$_…
Vibrational and magnetic properties of crystalline CuTe2O5
Y. V. Lysogorskiy, R. M. Eremina, T. P. Gavrilova +2
In the present work we have performed an ab initio calculation of vibrational properties of CuTe2O5 by means of density functional theory method. One has compared calculated values…
Pressure induced ferroelastic phase transition in LuLiF4 compound
Anastasia Petrova, Oleg Nedopekin, Dmitrii Tayurskii +1
The behavior of LuLiF4 sheelite (I41/a, Z = 4) under hydrostatic pressure was investigated by means of the first principles calculations. The ferroelastic phase transition from the…
Ab-initio studying of spin states of sodium cobaltate NaCoO
Y. Lysogorskiy, O. Nedopekin, S. Krivenko +2
Puzzling properties of sodium cobaltates NaCoO become an issue of numerous recent theoretical and experimental investigations because of very high thermopower and intri…
Gaussian fluctuations in an ideal bose-gas -- a simple model
A Petrova, O Nedopekin, D Tayurskii +1
Based on the canonical ensemble, we suggested the simple scheme for taking into account Gaussian fluctuations in a finite system of ideal boson gas. Within framework of scheme we i…
