Modalities od self-organized charge response in low dimensional systems

We present modalities of self-organized charge response in low dimensional systems, like diverse organic and quantum spin systems, studied by the low-frequency (10 mHz &#8211 ; ; 1 MHz) dielectric spectroscopy. Density wave structures with the order of commensurability N &raquo ; ; 4 can be recognized as phasons in a random impurity potential, whereas those with N &raquo ; ; 3 can be viewed as topological defects like charge domain wall pairs in the background domain structure.
