It is shown, here in the context of percolation, that one can have multifractal behavior and at the same time a single correlation length. This length sets the scale below which non-trivial scaling behavior occurs and it is controlled by a few relevant operators, as in ordinary critical...

A short review of the critical properties of 1/ƒ noise in percolating mixtures is presented, including continuum corrections and comparisons with experiments. The relation to multifractals and analogies with ordinary critical phenomena are recalled. New results on the effect of noisy insulators...
