超孤子:原子孤子链中的孤子激发

Supersolitons: Solitonic excitations in atomic soliton chains

David Novoa, Boris A. Malomed, Humberto Michinel, Victor M. Perez-Garcia

摘要:

我们表明,通过适当地调整物理相关的相互作用在两个组件的非线性薛定谔方程,它是可能实现的政权与粒子类孤子碰撞。这使我们能够构建一个类似的牛顿摆,也创造了局域集体激发的孤波链,这是准可积孤子,即超孤子。我们给出了一个物理解释的现象,支持它与微扰分析,并确认我们的预测直接模拟。

英文摘要:

We show that, by appropriately tuning physically relevant interactions in two-component nonlinear Schrodinger equations, it is possible to achieve a regime with particle-like solitonic collisions. This allows us to construct an analogue of the Newton's cradle and also to create localized collective excitations in solitary-wave chains which are quasi-integrable solitons, i.e. supersolitons. We give a physical explanation of the phenomenon, support it with a perturbative analysis, and confirm our predictions by direct simulations.
