Non-reciprocal interactions enhance heterogeneity [PDF]

open access: yesChaos, Solitons & Fractals, 2022
We study a process of pattern formation for a generic model of species anchored to the nodes of a network where local reactions take place, and that experience non-reciprocal long-range interactions, encoded by the network directed links. By assuming the system to exhibit a stable homogeneous equilibrium whenever only local interactions are considered,

Interaction induced non-reciprocal three-level quantum transport* [PDF]

open access: yesChinese Physics B, 2021
Besides its fundamental importance, non-reciprocity has also found many potential applications in quantum technology. Recently, many quantum systems have been proposed to realize non-reciprocity, but stable non-reciprocal process is still experimentally difficult in general, due to the needed cyclical interactions in artificial systems or operational ...

Introduction to quantum non-reciprocal interactions: from non-Hermitian Hamiltonians to quantum master equations and quantum feedforward schemes

open access: yesSciPost Physics Lecture Notes, 2022
These lecture notes from the 2019 Les Houches Summer School on Quantum Information Machines provides a pedagogical introduction to the theory of non-reciprocal quantum interactions and devices.

Medium Entropy Reduction and Instability in Stochastic Systems with Distributed Delay

open access: yesEntropy, 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.

Entropy production of nonreciprocal interactions

open access: yesPhysical 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 ...

Evolution of cooperation: combining kin selection and reciprocal altruism into matrix games with social dilemmas. [PDF]

open access: yesPLoS 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

open access: yesEPJ 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

open access: yesNew 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

Non-Invasive Brain Stimulation and Sex/Polypeptide Hormones in Reciprocal Interactions: A Systematic Review

open access: yesBiomedicines, 2023
A better understanding of interindividual differences and the development of targeted therapies is one of the major challenges of modern medicine. The sex of a person plays a crucial role in this regard.

Camp stability predicts patterns of hunter–gatherer cooperation [PDF]

open access: yesRoyal 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 ...
