多路网络中耦合非线性振子的爆炸同步

Explosive synchronization in coupled nonlinear oscillators on multiplex network

Umesh Kumar Verma, G. Ambika

摘要:

我们报告的爆炸同步的出现在一个多路复用网络中的第一层上的振荡器耦合的吸引力耦合和第二层上的,再加上排斥耦合。以Stuart-Landau和FitzHugh-Nagumo振子为节点动力学模型,考虑了非局域和平均场的层内耦合。我们建立了爆炸同步发生在多路复用网络中的高斯噪声的存在下,和过渡是一阶的滞后状态的完全层内和同相层间同步。滞后的宽度取决于层内吸引耦合的范围、层间耦合的强度和噪声。我们还看到如何控制这种诱导跃迁,以便通过调整排斥耦合或噪声的强度,将不期望的爆炸性质转换为连续类型。

英文摘要:

We report the emergence of explosive synchronization in a multiplex network where oscillators on the first layer are coupled with attractive coupling and those on the second layer, coupled with repulsive coupling. With Stuart-Landau and FitzHugh-Nagumo oscillators as the nodal dynamics, we consider non-local and mean-field intralayer couplings. We establish that explosive synchronization occurs in the multiplex network in the presence of Gaussian noise, and the transition is first order with hysteresis to a state of complete intra-layer and in-phase interlayer synchronization. The width of the hysteresis depends on the range of intralayer attractive coupling, strength of interlayer coupling and noise. We also see how to have control over this induced transition so that the explosive nature, if undesirable, can be converted to continuous type by tuning the strength of repulsive coupling or noise.
