1/f noise, disorder and dimensionality

E. Marinari , G. Paladin , G. Parisi , A. Vulpiani

We discuss the rôle of disorder and of the lower critical dimension in producing a 1/f spectrum. We present a numerical simulation for a bidimensional Ising spin glass, showing a 1/f spectrum in a remarkable range of temperatures and frequencies.
