We consider atoms interacting with each other through the topological structure of ac omplex network and investigate lattice vibrations of the system, the quanta of which we call netons for convenience. The density of neton levels, obtained numerically, reveals that unlike a local regular lattice, the system develops a gap of finite width, manifesting extreme rigidity of the network structure at low energies. Two different network models, the small-world network and the scale-free network, are…

Matching Rules for Collective Behaviors on Complex Networks: Optimal Configurations for Vibration Frequencies of Networked Harmonic Oscillators
The vibration spectra of the classical mass spring model with different masses on complex networks are studied, and it is found that becomes maximal and becomes minimal if the node degrees are point-to-point-positively correlated with the masses.

This article formalizes many of the Estrada indices proposed and studied in the mathematical literature serving as a guide for their further studies and analyses many of them computationally for small graphs as well as large complex networks.

This study shows how elastic constants are related to the topology of the network and how they can be derived from the equations of the dynamics at equilibrium and the introduction of the spring stiffness as an indicator of information propagation between nodes.
Optimal configuration for vibration frequencies in a ring of harmonic oscillators: The nonidentical mass effect
The parameter diversity effect in coupled nonidentical elements has attracted persistent interest in nonlinear dynamics. Of fundamental importance is the so-called optimal configuration problem for
Eigenvector Localization as a Tool to Study Small Communities in Online Social Networks
A mathematical procedure for identification of small "communities" or segments within large bipartite networks, based on spectral analysis of the matrix encoding network structure, is presented and discussed.


Emergence of scaling in random networks
A model based on these two ingredients reproduces the observed stationary scale-free distributions, which indicates that the development of large networks is governed by robust self-organizing phenomena that go beyond the particulars of the individual systems.
Evolution of networks
The recent rapid progress in the statistical physics of evolving networks is reviewed, and how growing networks self-organize into scale-free structures is discussed, and the role of the mechanism of preferential linking is investigated.
Collective dynamics of ‘small-world’ networks
Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

The spectral density shows an exponential decay around the center, followed by power-law long tails at both spectrum edges, and the mass gap scales as N(-0.68) and the component of the normalized eigenfunction at the hub is of order unity.
Statistical mechanics of complex networks
A simple model based on these two principles was able to reproduce the power-law degree distribution of real networks, indicating a heterogeneous topology in which the majority of the nodes have a small degree, but there is a significant fraction of highly connected nodes that play an important role in the connectivity of the network.
Exploring complex networks
This work aims to understand how an enormous network of interacting dynamical systems — be they neurons, power stations or lasers — will behave collectively, given their individual dynamics and coupling architecture.
Diffusion, localization and dispersion relations on “small-world” lattices
Abstract:The spectral properties of the Laplacian operator on “small-world” lattices, that is mixtures of unidimensional chains and random graphs structures are investigated numerically and
Phase ordering on small-world networks with nearest-neighbor edges.
It is found that in the appropriate regime phase ordering emerges at finite temperatures, even for a tiny fraction of shortcuts.
Synchronization on small-world networks.
Phase synchronization is observed to emerge in the presence of even a tiny fraction P of shortcuts and to display saturated behavior for P > or similar to 0.5, indicating that the same synchronizability as the random network (P=1) can be achieved with relatively small number of shortcuts.
