Static impurities in a weakly-interacting Bose gas
arXiv:2109.14931
Abstract
We present a comprehensive discussion of the ground-state properties of dilute -dimensional Bose gas interacting with a few static impurities. Assuming the short-ranged character of the boson-impurity interaction, we calculate the energy of three- and two-dimensional Bose systems with one and two impurities immersed.
