论文摘要
我们报告了两种组成部分中多个深色antidark soliton（dads）的静态和动力学特性，可抵抗相互作用的bose-Einstein冷凝物。由涉及多个父亲的实验观察结果的动机，我们提出了一项理论研究，该研究展示了在混合物的第一个（第二）组成部分中由黑暗（antidark）孤子组成的状态，用于不同的种间相互作用值。据发现，很少有爸爸的合奏可能是稳定的配置，而对于较大的爸爸阵列，相关的稳定窗口相对于种间相互作用强度逐渐变窄。此外，监测了由混合物的两个组成部分中交替的爸爸组成的状态的动态形成。观察到这些状态的复杂动力学演变，导致分类的爸爸或根据种间耦合的强度击败深色黑暗的孤子。这项研究证明了对爸爸配置的未来研究的明显途径。
We report on the static and dynamical properties of multiple dark-antidark solitons (DADs) in two-component, repulsively interacting Bose-Einstein condensates. Motivated by experimental observations involving multiple DADs, we present a theoretical study which showcases that bound states consisting of dark (antidark) solitons in the first (second) component of the mixture exist for different values of interspecies interactions. It is found that ensembles of few DADs may exist as stable configurations, while for larger DAD arrays, the relevant windows of stability with respect to the interspecies interaction strength become progressively narrower. Moreover, the dynamical formation of states consisting of alternating DADs in the two components of the mixture is monitored. A complex dynamical evolution of these states is observed, leading either to sorted DADs or to beating dark-dark solitons depending on the strength of the interspecies coupling. This study demonstrates clear avenues for future investigations of DAD configurations.
