摘要：

We consider wandering of a nonrelativistic particle in a time-dependent random potential in d spatial dimensions. Its root-mean-square displacement from the initial position increases superdiffusively with time t as t9/8 for d > 1, and as t6/5 in d = 1. Its kinetic energy increases at t1/2 for d > 1, and as t2/5 in d = 1. These scaling behaviors hold for both the classical and the corresponding quantum-mechanical problem in continuous space-time and differ from those of lattice models.
