A self-consistent system of maps for the analysis of spatial structures and their spectrum of small vibrations in a quantum chain of atoms in an external field at finite temperatures is derived. A numerical analysis of random structures and their stability is made. The local nature of the appearance of low-frequency vibrations is demonstrated.
