Query: Long-lasting Exponential Spreading in Periodically Driven Quantum
  Systems   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 pseudo-classical map, both
qualitatively and quantitatively. Possible applications of our findings are
also briefly discussed.
