Abstract
The existence of solitary excitations is shown through a quantum-mechanical model consisting of electronic two-level centers coupled to the lattice vibrations of the surrounding crystal. Simultaneously localized phonon modes appear in the region around these stable excitations. Within a time-dependent projection-operator formalism coupled equations of motion for the solitary waves and the phonons are derived.Keywords
