  • Grechnev, A.; Tretyak, S.M.; Freiman, Yu.A. (Физика низких температур, 2010)
    The lattice distortion parameter δ≡c/a – √8/3 has been calculated as a function of molar volume for the hcp phases of He, Ar, Kr, and Xe. Results from both semi-empirical potentials and density functional theory are ...
  • Tretyak, S.M.; Antsygina, T.N.; Freiman, Yu.A. (Физика низких температур, 2006)
    The hcp lattice distortion parameter δ, the deviation of c/a ratio from the ideal hcp value √ 8/3 , have been calculated for solid He under pressure taking into account two- and three-body interatomic forces. The resulting ...
  • Freiman, Yu.A.; Tretyak, S.M.; Jeżowski, A. (Физика низких температур, 2000)
    The magnetic properties of oxygen pair clusters are investigated theoretically for different cluster geometries which can be realized by doping molecular cryomatrices with oxygen. Anomalous temperature and pressure behavior ...
  • Freiman, Yu.A.; Tretyak, S.M. (Физика низких температур, 2007)
    The T 0K equations of state (EOS) of rare-gas solids (RGS) (He, Ne, Ar, Kr, and Xe) are calculated in the experimentally studied ranges of pressures accounting for two- and three-body interatomic forces. Solid-state ...
  • Freiman, Yu.A.; Tretyak, S.M.; Goncharov, A.F.; Mao, H.; Hemley, R.J. (Физика низких температур, 2011)
    The orientational order parameter, rotational ground-state energy, and lattice distortion parameter (the deviation of the c/a ratio from the ideal hcp value 1.633) in hcp lattice of phase I of p-H₂ and o-D₂ are calculated ...
  • Freiman, Yu.A.; Grechnev, A.; Tretyak, S.M.; Goncharov, Alexander F.; Gregoryanz, Eugene (Физика низких температур, 2015)
    We present results of lattice dynamics calculations of Poisson’s ratio (PR) for solid hydrogen and rare gas solids (He, Ne, Ar, Kr and Xe) under pressure. Using two complementary approaches — the semi-empirical many-body ...
  • Freiman, Yu.A.; Grechnev, Alexei (Физика низких температур, 2016)
    Analytical calculations of the potential barrier hindering rotation of the hydrogen molecules in the molecular field of neighboring molecules are performed for molecular solid hydrogen. The calculations are made for the ...
  • Freiman, Yu.A.; Grechnev, Alexei; Tretyak, S.M.; Goncharov, Alexander F.; Hemley, Russell J. (Физика низких температур, 2013)
    We present results of semi-empirical lattice dynamics calculations of the sound velocities in solid hydrogen under pressure based on the many-body intermolecular potential and first-principle density-functional theory ...
