1/f noise in bak-tang-wiesenfeld models on narrow stripes

Sergei Maslov, Chao Tang, Yi Cheng Zhang

Research output: Contribution to journalArticlepeer-review


We report our findings of a 1/f power spectrum for the total amount of sand in directed and undirected Bak-Tang-Wiesenfeld models confined to narrow stripes and driven locally. The underlying mechanism for the 1/f noise in these systems is an exponentially long configuration memory giving rise to a very broad distribution of time scales. Both models are solved analytically with the help of an operator algebra to explicitly show the appearance of the long configuration memory.
