  • Lattice distortion in hcp rare gas solids 
    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 ...
  • Poisson’s ratio in cryocrystals under pressure 
    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 ...
