Engineering quantum correlations to enhance transport in cold atoms

摘要

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