Resonant emission of solitons from impurity-induced localized waves in nonlinear lattices

Abstract: We propose a mechanism for soliton creation from resonantly excited localized waves via supratransmission in band gaps of nonlinear lattices. A nonlinear localized wave, which is formed by and vibrates around an impurity with an intrinsic frequency, is found to undergo a local resonance when subject to an external forcing. Under the resonance, an instability develops that leads to the efficient emission of solitons at a much lower rate than that in uniform lattices with no impurity.

“…This work presents a method for determining the NST threshold in non-integrable N-component systems by obtaining an asymptotic solution based on the linear decaying profile of a soliton with N parameters. The authors also propose a method for generating and studying the dynamics of spatial optical solitons in a birefringent medium with quadratic nonlinearity, which is developed in [28]. Technical terms are explained upon first usage and objective language is consistently used throughout the passage.…”

“…This concept initially developed on one-dimensional systems has been successfully applied on two-dimensional systems [4,5]. In addition to the initial periodic driven boundary, various ways to achieve supratransmission have also been proposed [6][7][8].…”

“…Продолжая вопрос кристаллических решеток, авторы [Yu, Wang, Tao, 2011] показали, что нелинейный резонанс на примесях делает локализованное возбуждение (обычно дискретный бризер) неустойчивым, что приводит к испусканию солитонов, которое выглядит совершенно иначе, чем при прямом возбуждении однородных нелинейных систем без примесей. Этот подход позволяет создавать солитоны при небольших значениях силы гармонического внешнего воздействия.…”
