Query: A ring accelerator for matter-wave solitons   We describe a new technique to accelerate and control a confined cloud of
ultracold neutral atoms. In our configuration, a Bose-Einstein Condensate
trapped in a ring is accelerated by using an amplitude-modulated optical
potential. The spreading of the atomic cloud is avoided by an adequate tuning
of the scattering length. We also discuss other variations that offer new
possibilities of robust control of atomic solitons. Our numerical results show
that this cold matter accelerator is easily accessible in the frame of current
experiments.
