Fermi resonance interface solitons
The nonlinear dynamics of the interface between two layers of organic semiconductors is discussed for the case of the Fermi resonance, which occurs when the energy fiaf of excitation on one side of the interface is approximately equal to 2Λω4, where fkob is the excitation energy on the other side. The Fermi resonance interaction across the interface gives rise to nonlinear plane waves, which propagate along the interface, and also to 2D solitons which are localized at the interface.
