    Density functional theory of a trapped Bose gas with tunable scattering length: From weak-coupling to unitarity

    We study an interacting Bose gas at T = 0 under isotropic harmonic confinement within Density Functional Theory in the Local Density approximation. The energy density functional, which spans the whole range of...
