Abstract
Using a dynamical model relevant to cold-atom experiments, we show that long-lasting exponential spreading of wave packets in momentum space is possible. Numerical results are explained via a pseudoclassical map, both qualitatively and quantitatively. Possible applications of our findings are also briefly discussed.Year: 2011 PMID： 22182094 DOI： 10.1103/PhysRevLett.107.234104
