    "abstract": "The evolution of a surface excitation in a two dimentional model is analyzed.\nI) It starts quadratically up to a spreading time t_{S}. II) It follows an\nexponential behavior governed by a self-consistent Fermi Golden Rule. III) At\nlonger times, the exponential is overrun by an inverse power law describing\nreturn processes governed by quantum diffusion. At this last transition time\nt_{R} a survival collapse becomes possible, bringing the survival probability\ndown by several orders of magnitude. We identify this strongly destructive\ninterference as an antiresonance in the time domain.",
