  • Ihor Yukhnovskii's 90th birthday 
    Автор відсутній (Condensed Matter Physics, 2015)
    On September 1, 2015 a prominent Ukrainian scholar, theoretical physicist, politician and a public figure, full member of the National Academy of Sciences, Doctor of Sciences in mathematics and physics, Professor, and ...
  • In memory of Eduard Vakarin 
    Автор відсутній (Condensed Matter Physics, 2015)
    On May 22, 2015 a sudden regrettable death took away Eduard Vakarin at an early age. Although Vakarin never held a prominent academic position, he established a reputation in the statistical mechanical theory of Condensed ...
  • Modeling the intermixing effects in highly strained asymmetric InGaAs/GaAs quantum well 
    Souaf, M.; Baira, M.; Maaref, H.; Ilahi, B. (Condensed Matter Physics, 2015)
    In this work, we have theoretically investigated the intermixing effect in highly strained In₀.₃Ga₀.₇As/GaAs QW taking into consideration the composition profile change resulting from in-situ indium surface segregation. ...
  • Molecular theory of solvation: Methodology summary and illustrations 
    Kovalenko, A. (Condensed Matter Physics, 2015)
    Integral equation theory of molecular liquids based on statistical mechanics is quite promising as an essential part of multiscale methodology for chemical and biomolecular nanosystems in solution. Beginning with a molecular ...
  • Numerical study of the spin-3/2 Ashkin-Teller model 
    Boudefla, R.; Bekhechi, S.; Hontinfinde, F. (Condensed Matter Physics, 2015)
    The study of the Ashkin-Teller model (ATM) of spin-3/2 on a hypercubic lattice is undertaken via Monte Carlo (MC) simulation. The phase diagrams are displayed and discussed in the physical parameter space. Rich physical ...
  • On relaxation phenomena in a two-component plasma 
    Gorev, V.N.; Sokolovsky, A.I.; Chelbaevsky, Z.Yu. (Condensed Matter Physics, 2015)
    The relaxation of the temperatures and velocities of the components of a quasi-equilibrium two-component homogeneous completely ionized plasma is investigated on the basis of a generalization of the Chapman--Enskog method ...
  • Quasiparticle electronic band structure of the alkali metal chalcogenides 
    Syrotyuk, S.V.; Shved, V.M. (Condensed Matter Physics, 2015)
    The electronic energy band spectra of the alkali metal chalcogenides M₂A (M: Li, Na, K, Rb; A: O, S, Se, Te) have been evaluated within the projector augmented waves (PAW) approach by means of the ABINIT code. The Kohn-Sham ...
  • Renormalized energy of ground and first excited state of Fröhlich polaron in the range of weak coupling 
    Tkach, M.V.; Seti, Ju.O.; Voitsekhivska, O.M.; Pytiuk, O.Yu. (Condensed Matter Physics, 2015)
    The partial summing of infinite range of diagrams for the two-phonon mass operator of polaron described by Frohlich Hamiltonian is performed using the Feynman-Pines diagram technique. The renormalized spectral parameters ...
  • Self-consistent approach for magnetic ordering and excited site occupation processes in a two-level system 
    Korynevskii, M.A.; Solovyan, V.B. (Condensed Matter Physics, 2015)
    Ferromagnetic ordering in a two-level partially excited system is studied in details. Magnitudes of magnetization (magnetic order parameter) and lattice ordering (excited level occupation number) are calculated self-consistently. ...
  • Thermodynamics and kinetics of solids fragmentation at severe plastic deformation 
    Khomenko, A.V.; Troshchenko, D.S.; Metlov, L.S. (Condensed Matter Physics, 2015)
    The approach of nonequilibrium evolution thermodynamics earlier offered is developed. It helps to describe the processes of defect formation within the adiabatic approximation. The basic equations system depends on the ...
  • The theory of a many boson system with the deformed Heisenberg algebra 
    Vakarchuk, I.O.; Panochko, G.I. (Condensed Matter Physics, 2015)
    We propose to consider nonlinear fluctuations in the theory of liquid ⁴He deforming the commutation relations between the generalized coordinates and momenta. The generalized coordinates are the coefficients of the density ...
  • The β-expansion of the D=1 fermionic spinless Hubbard model off the half-filling regime 
    Correa Silva, E.V.; Thomaz, M.T.; Rojas, O. (Condensed Matter Physics, 2015)
    We obtain that when the spinless model is off the half-filling regime (μ ≠ V), the Helmholtz free energy (HFE) can be written as two β-expansions: one expansion comes from the half-filling configuration and another one ...
  • Vibronic interaction in crystals with the Jahn-Teller centers in the elementary energy bands concept 
    Bercha, D.M.; Bercha, S.A.; Glukhov, K.E.; Sznajder, M. (Condensed Matter Physics, 2015)
    The order-disorder type phase transition caused by the vibronic interaction (collective Jahn-Teller effect) in a monoclinic CuInP₂S₆ crystal is analyzed. For this purpose, a trigonal protostructure model of CuInP₂S₆ is ...
