Statistical physics has proven to be a fruitful framework to describe phenomena outside the
realm of traditional physics. Recent years have witnessed an attempt by physicists to study …

Complex networks, comprised of individual elements that interact with each other through
reaction channels, are ubiquitous across many scientific and engineering disciplines …

Honeybee swarms and complex brains show many parallels in how they make decisions. In
both, separate populations of units (bees or neurons) integrate noisy evidence for …

Many real systems are made of strongly interacting networks, with profound consequences
on their dynamics. Here, we consider the case of two interacting social networks and, in the …

Fluctuations and noise may alter the behaviour of dynamical systems considerably. For
example, oscillations may be sustained by demographic fluctuations in biological systems …

Some of the most pivotal moments in intellectual history occur when a new ideology sweeps
through a society, supplanting an established system of beliefs in a rapid revolution of …

The effects of interpersonal interactions on individual's agreements result in a social
aggregation process which is reflected in the formation of collective states, as for instance …

The influence of contrarians on the noisy voter model is studied at the mean-field level. The
noisy voter model is a variant of the voter model where agents can adopt two opinions …

Analytical approaches in models of opinion formation have been extensively studied either
for an opinion represented as a discrete or a continuous variable. In this paper, we analyze …

We propose an opinion dynamics model based on Latané's social impact theory. Actors in
this model are heterogeneous and, in addition to opinions, are characterised by their varying …
