摘要：

We suggest a theory for the recently observed frequency dependent low temperature anomaly of the dielectric susceptibility epsilon in Charge and Spin Density Waves, emphasizing interference of collective and local type of pinning. The local pinning is characterized by metastable plastic deformations: neutral bisolitons or pairs of dislocation loops. The weak collective pinning is governed by the elasticity hardening due to Coulomb interaction.
