Abstract

The thermodynamic perturbation scheme for the very successful construction of classical liquid equations of state is applied in the quantum regime to the ground-state energy of a many-boson system interacting pairwise via a Lennard-Jones intermolecular potential. The ensuing density and attractive-coupling double expansion for the energy is series-analyzed with Padé techniques, as well as generalizations thereof. Results through sixth order compare with the Green Function Monte Carlo simulations for the same system at the one-percent level of accuracy.
