Query: Absence of Anderson localization in certain random lattices   We report on the transition between an Anderson localized regime and a
conductive regime in a 1D scattering system with correlated disorder. We show
experimentally that when long-range correlations, in the form of a power-law
spectral density with power larger than 2, are introduced the localization
length becomes much bigger than the sample size and the transmission peaks
typical of an Anderson localized system merge into a pass band. As other forms
of long-range correlations are known to have the opposite effect, i.e. to
enhance localization, our results show that care is needed when discussing the
effects of correlations, as different kinds of long-range correlations can give
rise to very different behavior.
