  text: "We present an optical setup with focus-tunable lenses to dynamically control
    the waist and focus position of a laser beam, in which we transport a trapped
    ultracold cloud of 87Rb over a distance of \r\n. The scheme allows us to shift
    the focus position at constant waist, providing uniform trapping conditions over
    the full transport length. The fraction of atoms that are transported over the
    entire distance comes near to unity, while the heating of the cloud is in the
    range of a few microkelvin. We characterize the position stability of the focus
    and show that residual drift rates in focus position can be compensated for by
    counteracting with the tunable lenses. Beyond being a compact and robust scheme
    to transport ultracold atoms, the reported control of laser beams makes dynamic
    tailoring of trapping potentials possible. As an example, we steer the size of
    the atomic cloud by changing the waist size of the dipole beam."
