Elastic anisotropy and Poisson's ratio of solid helium under pressure
A. Grechnev, S. M. Tretyak, Yu. A. Freiman +2
The elastic moduli, elastic anisotropy coefficients, sound velocities and Poisson's ratio of hcp solid helium have been calculated using density functional theory in generalized gr…

Lattice distortion in hcp rare gas solids
A. Grechnev, S. M. Tretyak, Yu. A. Freiman
The lattice distortion parameter has been calculated as a function of molar volume for the hcp phases of He, Ar, Kr and Xe. Results from both semi-empirica…
