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...

Two-step excitation of Rb atoms on He nanodroplets
We present the first sequential laser excitation of atom-doped helium nanodroplets. Rubidium atoms on the surface of helium nanodroplets are selectively excited with a continuous wave laser to the 52P1/2 state s...
