Ground-state properties and collective excitations in a 2D Bose-Einstein condensate with gravity-like interatomic attraction

Keleş, Ahmet; Sevinçli, Sevilay; Tanatar, Bilal (Springer, 2008)

We study the ground-state properties of a Bose-Einstein condensate (BEC) with the short-range repulsion and gravitylike 1/r interatomic attraction in two-dimensions (2D). Using the variational approach, we obtain the ...
