AI 中文摘要
我们研究在具有竞争型三次-五阶非线性的介质中传播的双分量包络内的准稳态环形孤子项链。孤子项链的亚稳态传播源于一个分量中相邻异相孤子间的排斥力，与另一分量平顶区域边界限制作用的平衡。数值模拟显示，即便给输入包络添加随机噪声，其亚稳态传播仍能覆盖约100个衍射长度；亚稳态项链中孤子的最大数量，可通过改变单个孤子的尺寸或调整承载项链的平顶区域宽度来控制。
英文摘要
We present quasistationary ring-shaped soliton necklaces in a two-component envelope propagating in a medium with competing cubic-quintic nonlinearity. Metastable propagation of soliton necklaces results from a balance of repulsion between adjacent out-of-phase solitons in one component and confinement by the boundary of a flattop region in the other. Numerical simulations demonstrate metastable propagation over about a hundred diffraction lengths, even with random noise added to the input envelopes. The maximum number of solitons in metastable necklaces can be controlled either by changing the size of individual solitons or by adjusting the width of the flattop region hosting the necklace.
