非局域耦合振子链中的图灵不稳定性

Turing instability in oscillator chains with non-local coupling

R. L. Viana, F. A. dos S. Silva, S. R. Lopes

摘要:

本文用解析和数值方法研究了非局域耦合的一维非线性振子链中发生图灵不稳定性的条件,使得耦合强度随空间距离呈幂律衰减.一个范围参数可以覆盖两个限制的情况下,本地(最近的邻居)和全球(所有到所有)的耦合。我们考虑一个非线性自催化反应扩散模型的例子。

英文摘要:

We investigate analytically and numerically the conditions for the Turing instability to occur in a one-dimensional chain of nonlinear oscillators coupled non-locally in such a way that the coupling strength decreases with the spatial distance as a power-law. A range parameter makes possible to cover the two limiting cases of local (nearest-neighbor) and a global (all-to-all) couplings. We consider an example from a non-linear auto-catalytic reaction-diffusion model.
