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.

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-reciprocal interactions spatially propagate fluctuations in a 2D Ising model
Journal of Statistical Mechanics: Theory and Experiment, 2023 Abstract Motivated by the anisotropic interactions between fish, we implement spatially anisotropic and therefore non-reciprocal interactions in the 2D Ising model. First, we show that the model with non-reciprocal interactions alters the system critical temperature away from that of the traditional 2D Ising model.

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.

Buckling of 2D Plasma Crystals with Non-reciprocal Interactions
, 2020 Laboratory realizations of 2D plasma crystals typically involve monodisperse microparticles confined into horizontal monolayers in radio-frequency (rf) plasma sheaths. This gives rise to the so-called plasma wakes beneath the microparticles. The presence of wakes renders the interactions in such systems non-reciprocal, a fact that can lead to a quite ...

Non-reciprocal interactions between K+ and Na+ ions in barley (Hordeum vulgare L.) [PDF]
Journal of Experimental Botany, 2008 The interaction of sodium and potassium ions in the context of the primary entry of Na(+) into plant cells, and the subsequent development of sodium toxicity, has been the subject of much recent attention. In the present study, the technique of compartmental analysis with the radiotracers (42)K(+) and (24)Na(+) was applied in intact seedlings of barley

Active particle condensation by non-reciprocal and time-delayed interactions [PDF]
The European Physical Journal E, 2018 We consider flocking of self-propelling agents in two dimensions, each of which communicates with its neighbors within a limited vision cone. Also, the communication occurs with some delay. The communication among the agents are modeled by Vicsek rules. In this study we explore the effect of non-reciprocal interaction among the agents, induced by their

Optimizing strategic blocks with asymmetric bilateral propensities with symmetric propensities
Entreciencias: Diálogos en la Sociedad del Conocimiento, 2013 There are models taken from physics that have been used to explain the formation of coalitions or blocks of agents. Such models are useful to understand how alliances (in wars, political parties, etc.) tend to cluster friends in same blocks and enemies ...

Non-reciprocal interactions drive emergent chiral crystallites [PDF]
We study a new type of 2D active material that exhibits macroscopic phases with two emergent broken symmetries: self-propelled achiral particles that form dense hexatic clusters, which spontaneously rotate. We experimentally realise active colloids that self-organise into both polar and hexatic crystallites, exhibiting exotic emergent phenomena.
