Entropy production of nonreciprocal interactions
Physical Review Research, 2023 Non-reciprocal interactions are present in many systems out of equilibrium. The rate of entropy production is a measure that quantifies the time irreversibility of a system, and thus how far it is from equilibrium. In this work, we introduce a non-motile active particle system where activity originates from asymmetric, pairwise interaction forces that ...

Medium Entropy Reduction and Instability in Stochastic Systems with Distributed Delay
Entropy, 2021 Many natural and artificial systems are subject to some sort of delay, which can be in the form of a single discrete delay or distributed over a range of times.

Evolution of cooperation: combining kin selection and reciprocal altruism into matrix games with social dilemmas. [PDF]
PLoS ONE, 2013 Darwinian selection should preclude cooperation from evolving; yet cooperation is widespread among organisms. We show how kin selection and reciprocal altruism can promote cooperation in diverse 2×2 matrix games (prisoner's dilemma, snowdrift, and hawk ...

Temporal patterns of reciprocity in communication networks
EPJ Data Science, 2023 Human communication, the essence of collective social phenomena ranging from small-scale organizations to worldwide online platforms, features intense reciprocal interactions between members in order to achieve stability, cohesion, and cooperation in ...

Clustering and flocking of repulsive chiral active particles with non-reciprocal couplings
New Journal of Physics, 2022 Recently, non-reciprocal systems have become a focus of growing interest. Examples occur in soft and active matter, but also in engineered quantum materials and neural (brain) networks. Here, we investigate the impact of non-reciprocity on the collective

Camp stability predicts patterns of hunter–gatherer cooperation [PDF]
Royal Society Open Science, 2016 Humans regularly cooperate with non-kin, which has been theorized to require reciprocity between repeatedly interacting and trusting individuals. However, the role of repeated interactions has not previously been demonstrated in explaining real-world ...

Frontiers in Physics, 2023 Swimming at the microscale typically involves two modes of motion: mechanical propulsion and propulsion due to field interactions. During mechanical propulsion, particles swim by reconfiguring their geometry.

Non-reciprocity across scales in active mixtures
Nature Communications, 2023 In active matter, particles typically experience mediated interactions, which are not constrained by Newton’s third law and are therefore generically non-reciprocal.

A New Real-Life Test for Reciprocity in Autistic Adults: The Interactive Drawing Test
Frontiers in Psychiatry, 2022 Impaired social-emotional reciprocity is a defining feature of Autism Spectrum Disorder (ASD). Deficits in reciprocity can be difficult to assess, particularly in adults with average or above average intelligence.
