Optimal trap shape for a Bose gas with attractive interactions
arXiv:cond-mat/0601512 · doi:10.1103/PhysRevA.72.063611
Abstract
Dilute Bose gas with attractive interactions is considered at zero temperature, when practically all atoms are in Bose-Einstein condensate. The problem is addressed aiming at answering the question: What is the optimal trap shape allowing for the condensation of the maximal number of atoms with negative scattering lengths? Simple and accurate analytical formulas are derived allowing for an easy analysis of the optimal trap shapes. These analytical formulas are the main result of the paper.
