Coulombian disorder in Charge Density Waves

Résumé

When unscreened charged impurities are introduced in charge density wave system the long wavelength component of the disorder is long ranged and dominates static correlation functions. We calculate the x-ray intensity and find that it is identical to the one produced by thermal fluctuations in a disorder-free smectic-A. We suggest that this effect could be observed in the blue bronze material K$_{0.3}$MoO$_3$ doped with charged impurities such as Vanadium.
