摘要：

We demonstrate for various systems that the variance of a wave packet M(t)proportional tot(v), can show a superballistic increase with 2<v<less than or equal to>3, for parametrically large time intervals. A model is constructed that explains this phenomenon and its predictions are verified numerically for various disordered and quasiperiodic systems.
