Active matter synchronization and synergetics

Frank Schweitzer, Georges Andres, Adrien Baut +3

We study the collective behavior in a stochastic agent-based model of active matter. Provided a critical take-up of energy, agents produce two types of goods , that follow a…

Empirical Networks are Sparse: Enhancing Multi-Edge Models with Zero-Inflation

Giona Casiraghi, Georges Andres

Real-world networks are sparse. As we show in this article, even when a large number of interactions is observed, most node pairs remain disconnected. We demonstrate that classical…

Disentangling the Timescales of a Complex System: A Bayesian Approach to Temporal Network Analysis

Giona Casiraghi, Georges Andres

Changes in the timescales at which complex systems evolve are essential to predicting critical transitions and catastrophic failures. Disentangling the timescales of the dynamics g…

Modeling social resilience: Questions, answers, open problems

Frank Schweitzer, Georges Andres, Giona Casiraghi +5

Resilience denotes the capacity of a system to withstand shocks and its ability to recover from them. We develop a framework to quantify the resilience of highly volatile, non-equi…

Reconstructing signed relations from interaction data

Georges Andres, Giona Casiraghi, Giacomo Vaccario +1

Positive and negative relations play an essential role in human behavior and shape the communities we live in. Despite their importance, data about signed relations is rare and com…

Social nucleation: Group formation as a phase transition

Frank Schweitzer, Georges Andres

The spontaneous formation and subsequent growth, dissolution, merger and competition of social groups bears similarities to physical phase transitions in metastable finite systems.…
