Signal propagation in complex networks drives epidemics, is responsible for information
going viral, promotes trust and facilitates moral behavior in social groups, enables the …

Network science has evolved into an indispensable platform for studying complex systems.
But recent research has identified limits of classical networks, where links connect pairs of …

Recent decades have seen a rise in the use of physics methods to study different societal
phenomena. This development has been due to physicists venturing outside of their …

The complexity of many biological, social and technological systems stems from the richness
of the interactions among their units. Over the past decades, a variety of complex systems …

Reputation and reciprocity are key mechanisms for cooperation in human societies, often
going hand in hand to favor prosocial behavior over selfish actions. Here we review recent …

The constituents of many complex systems are characterized by non-trivial connectivity
patterns and dynamical processes that are well captured by network models. However, most …

One-shot anonymous unselfishness in economic games is commonly explained by social
preferences, which assume that people care about the monetary pay-offs of others …

A second wave pandemic constitutes an imminent threat to society, with a potentially
immense toll in terms of human lives and a devastating economic impact. We employ the …

We live and cooperate in networks. However, links in networks only allow for pairwise
interactions, thus making the framework suitable for dyadic games, but not for games that …
