相干结构的相干结构的出现:非线性系统中的局域态

The emergence of a coherent structure for coherent structures: localized states in nonlinear systems

Jonathan Dawes

摘要:

相干结构出现在许多种耗散的、外部驱动的非线性系统的动力学中,并不断引发新的问题,挑战我们的物理和数学理解。在这类问题的一个特定子类中,出现了图案形成或“图灵”不稳定性,最近我们对局域态形成的理解取得了快速进展:规则图案的补丁被未图案化的均匀背景状态包围。这篇简短的评论文章调查了局部化状态所取得的进展,提出了这些想法的三个应用领域,这些想法将把理论带到新的方向,并最终对应用科学领域产生重大影响。最后,我提供了未来工作的猜测,基于本地化的状态,这可能有助于研究人员更普遍地理解相干结构。

英文摘要:

Coherent structures emerge from the dynamics of many kinds of dissipative, externally driven, nonlinear systems, and continue to provoke new questions that challenge our physical and mathematical understanding. In one specific sub-class of such problems, where a pattern-forming, or `Turing', instability occurs, rapid progress has been made recently in our understanding of the formation of localized states: patches of regular pattern surrounded by the unpatterned homogeneous background state. This short review article surveys the progress that has been made for localized states, proposes three areas of application for these ideas that would take the theory in new directions and ultimately be of substantial benefit to areas of applied science. Finally I offer speculations for future work, based on localized states, that may help researchers to understand coherent structures more generally.
