Abstract

It is well-understood that the network structure of complex systems affects their robustness; the role played by the shape of spatially embedded networks, however, is less explored. Here, we study the robustness of networks where links are physical objects or physically transfer some quantity, hence the links can be disrupted at any point along their trajectory. To model physical damage, we tile each network with boxes and we sequentially damage these boxes, removing any link from the network that intersects a damaged tile. Using model and empirical networks, we systematically explore how the layout and the structure of networks jointly affect the resulting percolation transition. For example, we analytically and numerically show that randomly damaging a vanishing fraction of tiles is enough to destroy large-scale connectivity in randomly embedded networks. This demonstrates that the presence of long-range links makes networks extremely vulnerable to physical damage. Our work contributes to the emergent theory of physical networks.

网络因物理损坏而解体。
众所周知,复杂系统的网络结构影响其鲁棒性;然而,空间嵌入网络的形状所起的作用却很少被探索。在这里,我们研究网络的鲁棒性,其中链接是物理对象或物理传输一些量,因此链接可以在其轨迹上的任何点中断。为了模拟物理损伤,我们将每个网络都铺上盒子,并依次损坏这些盒子,从网络中删除与受损砖块相交的任何链接。利用模型和经验网络,我们系统地探讨了网络的布局和结构如何共同影响由此产生的渗透转变。例如,我们的分析和数值表明,随机破坏一个消失的碎片足以破坏随机嵌入网络中的大规模连通性。这表明,远程链路的存在使网络极易受到物理损坏。我们的工作有助于物理网络的涌现理论。

期刊介绍: Communications Physics is an open access journal from Nature Research publishing high-quality research, reviews and commentary in all areas of the physical sciences. Research papers published by the journal represent significant advances bringing new insight to a specialized area of research in physics. We also aim to provide a community forum for issues of importance to all physicists, regardless of sub-discipline. The scope of the journal covers all areas of experimental, applied, fundamental, and interdisciplinary physical sciences. Primary research published in Communications Physics includes novel experimental results, new techniques or computational methods that may influence the work of others in the sub-discipline. We also consider submissions from adjacent research fields where the central advance of the study is of interest to physicists, for example material sciences, physical chemistry and technologies.
