Modeling Explosive Opinion Depolarization in Interdependent Topics
Jaume Ojer, Michele Starnini, Romualdo Pastor-Satorras
Understanding the dynamics of opinion depolarization is pivotal to reducing the political divide in our society. We propose an opinion dynamics model, which we name the social comp…
Flocking dynamics mediated by weighted social networks
Jaume Ojer, Romualdo Pastor-Satorras
We study the effects of animal social networks with a weighted pattern of interactions on the flocking transition exhibited by models of self-organized collective motion. Consideri…
The advantage of self-protecting interventions in mitigating epidemic circulation at the community level
Romualdo Pastor-Satorras, Claudio Castellano
Protecting interventions of many types (both pharmaceutical and non-pharmaceutical) can be deployed against the spreading of a communicable disease, as the worldwide COVID-19 pande…
Scale-free behavioral cascades and effective leadership in schooling fish
Julia Mugica, Jordi Torrents, Javier Cristin +3
Behavioral contagion and the presence of behavioral cascades are natural features in groups of animals showing collective motion, such as schooling fish or grazing herbivores. Here…
Cumulative Merging Percolation: A long-range percolation process in networks
Lorenzo Cirigliano, Giulio Cimini, Romualdo Pastor-Satorras +1
Percolation on networks is a common framework to model a wide range of processes, from cascading failures to epidemic spreading. Standard percolation assumes short-range interactio…
