N2 - We show experimentally that precise phase modulation of an optical potential allows us to control quantum correlations for atomic wave packets in a way that greatly enhances momentum transport. Experimentally, this means that for the same laser power and pulse frequency, atoms are accelerated to much higher energies. We explain our results with a pseudoclassical analysis along with numerical simulations, highlighting the existence of transporting islands in phase space.
