Abstract
Incommensurate systems are in general very sensitive to impurities of various kinds. Phenomenological models are reviewed, which are used for the description of the impurity pinning of modulated structures. Theoretical results concerning the destruction of long-range incommensurate order, the influence of impurities on low-frequency dynamics and on the lock-in transition, as well as hysteresis effects induced by impurities are discussed.Keywords
