Solid helium (3He and 4He) in the hcp and fcc phases has been studied by the path-integral Monte Carlo technique. Simulations were carried out in the isothermal–isobaric (NPT) ensemble at pressures up to 52 GPa. This allows one to study the temperature and pressure dependences of isotopic effects on the crystal volume and vibrational energy in a wide parameter range. The obtained equation of state at room temperature agrees with available experimental data. The kinetic energy, Ek, of solid… Expand

The Lennard-Jones Potential Revisited: Analytical Expressions for Vibrational Effects in Cubic and Hexagonal Close-Packed Lattices.
TLDR
Analytical formulas are derived for the zero-point vibrational energy and anharmonicity corrections of the cohesive energy and the mode Grüneisen parameter within the Einstein model for the cubic lattices and for the hexagonal close-packed structure, giving qualitative but nevertheless deep insight into vibrational effects in solids.

Full-configuration-interaction calculation of three-body nonadditive contribution to helium interaction potential.
TLDR
The present complete three-body fit is a fivefold improvement over the previous best potential, and the FCI contribution beyond CCSD(T) is rather important, being of the same order of magnitude as the uncertainty of the sum of two-body interactions. Expand

TLDR
Single-crystal X-ray diffraction measurements on solid He-4 demonstrate that the structure of the solid is hexagonal close packed over this pressure-temperature range, contrary to both the interpretation of high-pressure optical studies and to theoretical predictions. Expand
