Abstract
Coherent soliton states are analysed using the equivalent Boson Hamilt onian for excitons. This equivalent Hamiltonian includes the exciton c oncentrations corresponding to the Tyablikov approximation in the theo ry oi magnetism. Soliton spectra were derived depending on the intensi ty of light source that creates solitons. Increased exciton concentrat ion enhances the soliton stability.
