TL;DR: In this paper, the properties of a weakly interacting Bose gas of hard spheres in three dimensions were studied in the framework of the correlated basis functions (CBF) approximation, and the results were compared with explicit expressions for the same quantities derived within the Bogoliubov model.
Abstract: Static and dynamic properties of a weakly interacting Bose gas of Hard Spheres in three dimensions are studied in the framework of the Correlated Basis Functions (CBF) approximation. Results are compared with explicit expressions for the same quantities derived within the Bogoliubov model. Despite the good agreement in the energy of the groundstate and the excited states, other quantities such as the dynamic structure function present important differences that become more significant when the density is raised.
