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…

Poisson's ratio in cryocrystals under pressure
Yu. A. Freiman, Alexei Grechnev, S. M. Tretyak +2
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 a…
