DYNAMICS OF FERMI RESONANCE SOLITARY WAVES PROPAGATING ALONG 2 INTERFACES

The dynamics of Fermi resonance solitary waves propagating along two p arallel interfaces in a layered organic semiconductor system is invest igated both analytically and numerically. It is shown that the interac tion between solitary waves leads to their attraction or repulsion, de pending on their initial phase difference. In the case of attraction t he solitary waves create a bound state, and their centers oscillate in time with respect to their common mass center. The corresponding peri od of oscillations is calculated. It is found that the amplitudes and widths of the solitary waves also oscillate in time.
