Physical networks as networks of networks

Physical networks are spatially embedded complex networks composed of nodes 
and links that are physical objects which cannot overlap. Examples of 
physical networks range from neural networks and interacting biomolecules to 
pore networks and disordered metamaterials. It is hypothesized that the 
distinctive features of physical networks, such as the non-trivial shape of 
nodes and links and volume exclusion affect their network structure and 
function. However, the traditional tool set of network science cannot capture 
these properties, calling for a suitable generalization of network theory. 
Here, I present recent efforts to understand the impact of physicality 
through analytically solvable models of both network assembly and dynamics on 
them.
I represent physical networks as network-of-networks: each extended physical 
node is modeled by a network embedded in space, these subnetworks are bound 
together to form a larger network. I will exploit this representation to 
discuss three topics: (i) a network growth model that builds physical 
networks from random walk trajectories, (ii) diffusion dynamics and 
localization transitions driven by correlations between physical and network 
properties, and (iii) modeling degradation of physical networks using split 
percolation. Throughout, the goal is to strike a balance between analytical 
tractability and physical realism.
