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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
