Abstract
Dislocations and aggregation of solitons in Charge Density Waves (CDW) at low temperatures are considered. The principal effects of Coulomb interactions are studied both at zero temperature and in the presence of residual carriers. The energy and distributions of phase deformations and of electric field, the interactions with solitons are found. The conditions for solitons aggregating into larger complexes equivalent to dislocation loops are found. The results provide an insight onto sequential steps of the current conversion in CDW crystals.
