✦ Synopsis

Coherent soliton states are analysed using the equivalent Boson Hamiltonian for excitons. This equivalent Hamiltonian includes the exciton concentrations corresponding to the Tyablikov approximation in the theory of magnetism. Soliton spectra were derived depending on the intensity oflight source that creates solitons. Increased exciton concentration enhances the soliton stability.
