A toy model for approaching volcanic plumbing systems as complex systems
Remy Cazabet, Catherine Annen, Jean-Francois Moyen +1
Magmas form at depth, move upwards and evolve chemically through a combination of processes. Magmatic processes are investigated by means of fieldwork combined with geophysics, geo…
The politics of physicists social models
Pablo Jensen
I give an overview of the topic of this special issue, the applications of (statistical) physics to social sciences at large. I discuss several examples of simple social models put…
In social complex systems, the whole can be more or less than (the sum of) the parts
Eric Bertin, Pablo Jensen
We discuss in a statistical physics framework the idea that ``the whole is less than the parts'', as sometimes advocated by sociologists in view of the intrinsic complexity of huma…
Reentrant phase transitions in threshold driven contagion on multiplex networks
Samuel Unicomb, Gerardo Iñiguez, János Kertész +1
Models of threshold driven contagion explain the cascading spread of information, behavior, systemic risk, and epidemics on social, financial and biological networks. At odds with…
Giant catalytic effect of altruists in Schelling's segregation model
P. Jensen, T. Matreux, J. Cambe +2
We study the effect of introducing altruistic agents in a Schelling-like model of residential segregation. We find that even an infinitesimal proportion of altruists has dramatic c…
Threshold driven contagion on weighted networks
Samuel Unicomb, Gerardo Iñiguez, Márton Karsai
Weighted networks capture the structure of complex systems where interaction strength is meaningful. This information is essential to a large number of processes, such as threshold…
Burstiness and tie reinforcement in time varying social networks
Enrico Ubaldi, Alessandro Vezzani, Marton Karsai +2
We introduce a time-varying network model accounting for burstiness and tie reinforcement observed in social networks. The analytical solution indicates a non-trivial phase diagram…
User-based representation of time-resolved multimodal public transportation networks
Laura Alessandretti, Márton Karsai, Laetitia Gauvin
Multimodal transportation systems can be represented as time-resolved multilayer networks where different transportation modes connecting the same set of nodes are associated to di…
Asymptotic theory for the dynamic of networks with heterogenous social capital allocation
Enrico Ubaldi, Nicola Perra, Márton Karsai +3
The structure and dynamic of social network are largely determined by the heterogeneous interaction activity and social capital allocation of individuals. These features interplay…
Kinetics of Social Contagion
Zhongyuan Ruan, Gerardo Iniguez, Marton Karsai +1
Diffusion of information, behavioral patterns or innovations follows diverse pathways depending on a number of conditions, including the structure of the underlying social network,…
The role of endogenous and exogenous mechanisms in the formation of R&D networks
Mario Vincenzo Tomasello, Nicola Perra, Claudio Juan Tessone +2
We develop an agent-based model of strategic link formation in Research and Development (R&D) networks. Empirical evidence has shown that the growth of these networks is driven by…
Metapopulation epidemic models with heterogeneous mixing and travel behaviour
Andrea Apolloni, Chiara Poletto, Jose' J. Ramasco +2
The complex interplay between population movements in space and non-homogeneous mixing patterns have so far hindered the fundamental understanding of the conditions for spatial inv…
On the emergence of an "intention field" for socially cohesive agents
Jean-Philippe Bouchaud, Christian Borghesi, Pablo Jensen
We argue that when a social convergence mechanism exists and is strong enough, one should expect the emergence of a well defined "field", i.e. a slowly evolving, local quantity aro…
Contraction of online response to major events
Michael Szell, Sebastian Grauwin, Carlo Ratti
Quantifying regularities in behavioral dynamics is of crucial interest for understanding collective social events such as panics or political revolutions. With the widespread use o…
Emergence of hierarchy in cost driven growth of spatial networks
Rémi Louf, Pablo Jensen, Marc Barthelemy
One of the most important features of spatial networks such as transportation networks, power grids, Internet, neural networks, is the existence of a cost associated with the lengt…
Opinion groups formation and dynamics : structures that last from non lasting entities
Sébastian Grauwin, Pablo Jensen
We extend simple opinion models to obtain stable but continuously evolving communities. Our scope is to meet a challenge raised by sociologists of generating "structures that last…
Effective Free Energy for Individual Dynamics
Sebastian Grauwin, Dominic Hunt, Eric Bertin +1
Physics and economics are two disciplines that share the common challenge of linking microscopic and macroscopic behaviors. However, while physics is based on collective dynamics,…
Competition between collective and individual dynamics
Sébastian Grauwin, Eric Bertin, Rémi Lemoy +1
Linking the microscopic and macroscopic behavior is at the heart of many natural and social sciences. This apparent similarity conceals essential differences across disciplines: wh…
