脉冲耦合振荡器自适应网络中的巡游嵌合体

Itinerant chimeras in an adaptive network of pulse-coupled oscillators

Dmitry Kasatkin, Vladimir Klinshov, Vladimir Nekorkin

摘要:

在具有自适应耦合的脉冲耦合振荡器网络中,我们将形成一种称为“巡游嵌合体”的动力学状态。与经典的嵌合体状态类似,网络分裂为两个域,相干域和非相干域。最大的区别在于畴的组成是不稳定的,即振荡器表现出畴之间的自发切换。这个过程可以被看作是振荡器从一个域到另一个域的移动,或者是嵌合体核心在网络中的移动。我们探讨了巡游嵌合体的基本特征,如核心大小的均值和方差,以及核心内的振子寿命。我们还研究了系统的标度行为,并表明所观察到的制度是不是一个有限大小的影响,但集体动力学的一个关键特征,即使在大型网络中仍然存在。

英文摘要:

In a network of pulse-coupled oscillators with adaptive coupling, we a dynamical regime which we call an `itinerant chimera'. Similarly as in classical chimera states, the network splits into two domains, the coherent and the incoherent ones. The drastic difference is that the composition of the domains is volatile, i.e. the oscillators demonstrate spontaneous switching between the domains. This process can be seen as traveling of the oscillators from one domain to another, or as traveling of the chimera core across network. We explore the basic features of the itinerant chimeras, such as the mean and the variance of the core size, and the oscillators lifetime within the core. We also study the scaling behavior of the system and show that the observed regime is not a finite-size effect but a key feature of the collective dynamics which persists even in large networks.
