Universal 1/f Noise from Dissipative SOC Models
P. De Los Rios, Y. -C. Zhang
Abstract
We introduce a model able to reproduce the main features of 1/f noise: hyper-universality (the power-law exponents are independent on the dimension of the system; we show here results in d=1,2) and apparent lack of a low-frequency cutoff in the power spectrum. Essential ingredients of this model are an activation-deactivation process and dissipation.
