论文摘要
堆积物是具有同时存在群和同步的实体,由于相位和空间动力学之间令人着迷的双向相互作用,揭示了新兴的集体行为。尽管已经考虑了不同的耦合拓扑,但在这里,我们引入了随机变化的竞争期相互作用,在伴侣群中,有吸引力和排斥耦合的基础连接取决于视觉(传感)半径。除了调查一些基本特性,例如保护中心和避免碰撞外,我们还仔细检查了视力半径极限的情况。有吸引力的抑制性竞争相位耦合的同意可以探索各种渐近状态,例如静态$π$和混合相波状态,我们通过详细的数值分析探索这些状态的可行路线。在有吸引力的局部耦合的唯一存在中,我们揭示了静态簇同步的发生,其中簇数的数量至关重要地取决于每个伴侣的位置和相位的初始分布。此外,我们通过分析计算静态同步状态出现的足够条件。我们进一步报告了静态环相波状态的外观,并理论上评估了其半径。最后,我们使用Stuart-Landau振荡器来验证我们的发现,以描述受到有吸引力的局部耦合的堆积物的相动态。
Swarmalators are entities with the simultaneous presence of swarming and synchronization that reveal emergent collective behavior due to the fascinating bidirectional interplay between phase and spatial dynamics. Although different coupling topologies have already been considered, here we introduce time-varying competitive phase interaction among swarmalators where the underlying connectivity for attractive and repulsive coupling varies depending on the vision (sensing) radius. Apart from investigating some fundamental properties like conservation of center of position and collision avoidance, we also scrutinize the cases of extreme limits of vision radius. The concurrence of attractive-repulsive competitive phase coupling allows the exploration of diverse asymptotic states, like static $π$, and mixed phase wave states, and we explore the feasible routes of those states through a detailed numerical analysis. In sole presence of attractive local coupling, we reveal the occurrence of static cluster synchronization where the number of clusters depends crucially on the initial distribution of positions and phases of each swarmalator. In addition, we analytically calculate the sufficient condition for the emergence of the static synchronization state. We further report the appearance of the static ring phase wave state and evaluate its radius theoretically. Finally, we validate our findings using Stuart-Landau oscillators to describe the phase dynamics of swarmalators subject to attractive local coupling.
