heal.abstract | We describe the time evolution of a quantum wavepacket at the Anderson metal-insulator transition using a quasirandom model as an example of a system with a mobility edge. It is demonstrated that the dynamical wavefuunction is multifractal characterized by a continuous set of generalized spectral dimensions mu(q) and we find its alpha - f(alpha) spectra. We also define and calculate an infinite hierarchy of diffusion exponents gamma(q) corresponding to all the displacement moments (\r(t)\q) describing the quantum evolution. A slow subdiffusive decay for the 'staying at the origin probability' (P(t)) averaged over all initial sites is obtained at the mobility edge. | en |
