Ground-state energy and depletions for a dilute binary Bose gas
Andre Eckardt, Christoph Weiss, Martin Holthaus
When calculating the ground-state energy of a weakly interacting Bose gas with the help of the customary contact pseudopotential, one meets an artifical ultraviolet divergence whic…

Ground state energy of a homogeneous Bose-Einstein condensate beyond Bogoliubov
Christoph Weiss, Andre Eckardt
The standard calculations of the ground-state energy of a homogeneous Bose gas rely on approximations which are physically reasonable but difficult to control. Lieb and Yngvason [P…
