Phys. Rev. E 64, 012301 (2001) [3 pages]Superballistic spreading of wave packetsSee Also: Erratum Received 10 January 2001; published 13 June 2001 We demonstrate for various systems that the variance of a wave packet M(t)∝tν, can show a superballistic increase with 2<ν<~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. © 2001 The American Physical Society URL:
