Abstract

A theory of an acoustic vector soliton of the Love wave is constructed. The nonlinear Love wave propagating along the interface between of a plane surface layer and the elastic semi-space under the condition of acoustic self-induced transparency is investigated. A thin resonance transition layer containing paramagnetic impurity atoms or semiconductor quantum dots sandwiched between these two connected media. Explicit analytical expressions for the profile and parameters of the Love vector soliton are obtained. It is shown that the properties of the nonlinear Love wave depends on the parameters of the transition resonance layer, the connected elastic media and the transverse structure of the Love mode. Numerical investigations of the Love vector soliton is executed for the parameters of the layered structure ZnO/LiNbO_{3} and surface acoustic waves which can be reached in current experiments.
