Ground-State Parameters for the Quasi-Two-Dimensional Close-PackedHe4Solid at High Density
Physical review. A, General physics
A theoretical calculation of the chemical potential, spreading pressure, and inverse compressibility at O"K is reported for He 4 adsorbed on a graphite-like substrate for monolayer densities of 0.10 to 0.13 A -2. These functions are obtained from a ground-state variational wave function constructed of single-particle functions multiplied by Jastrow correlation factors. Use was made of a cluster expansion in the calculation of the ground-state energy. The theoretical results agree quite well with the empirical values.doi:10.1103/physreva.8.3065 fatcat:ttahzu4prbfhzmnx7knhz6ekau
