Power spectrum of rare events in two-dimensional BTW model, violation of noise hypothesis
Z. Moghadam, M. N. Najafi, A. Saber +1
One of the primitive aims of the two-dimensional BTW model had been to explain the noise which is widely seen in the natural systems. In this paper we study some time signa…
