Interpreting neural operators: How nonlinear waves propagate in nonreciprocal solids

J Colen, A Poncet, D Bartolo, V Vitelli - Physical Review Letters, 2024 - APS
We present a data-driven pipeline for model building that combines interpretable machine
learning, hydrodynamic theories, and microscopic models. The goal is to uncover the …

Dynamical structures in phase-separating nonreciprocal polar active mixtures

KL Kreienkamp, SHL Klapp - Physical Review E, 2024 - APS
Nonreciprocal systems exhibit diverse dynamical phases whose character depends on the
type and degree of nonreciprocity. In this study, we theoretically investigate dynamical …

Phase Transitions in single species Ising Models with Non-Reciprocal couplings

A Garcés, D Levis - arXiv preprint arXiv:2411.03544, 2024 - arxiv.org
We present a general framework for incorporating non-reciprocal interactions into the Ising
model with Glauber dynamics, without requiring multiple species. We then focus on a model …

Chiral quantum optics: recent developments, and future directions

DG Suárez-Forero, MJ Mehrabad, C Vega… - arXiv preprint arXiv …, 2024 - arxiv.org
Chiral quantum optics is a growing field of research where light-matter interactions become
asymmetrically dependent on momentum and spin, offering novel control over photonic and …

Emergent complex phases in a discrete flocking model with reciprocal and non-reciprocal interactions

M Mangeat, S Chatterjee, JD Noh, H Rieger - arXiv preprint arXiv …, 2024 - arxiv.org

a discrete-symmetry counterpart of the continuous-symmetry two-species Vicsek model …

Solving the Kinetic Ising Model with Non-Reciprocity

G Weiderpass, M Sharma, S Sethi - arXiv preprint arXiv:2410.23615, 2024 - arxiv.org
Non-reciprocal interactions are a generic feature of non-equilibrium systems. We define a
non-reciprocal generalization of the kinetic Ising model in one spatial dimension. We solve …

An Exact Solution for the Kinetic Ising Model with Non-Reciprocity

G Weiderpass, M Sharma, S Sethi - arXiv preprint arXiv:2411.00059, 2024 - arxiv.org
A wide range of non-equilibrium phenomena in nature involve non-reciprocal interactions.
To understand the novel behaviors that can emerge in such systems, finding tractable …

T Hempel, SAM Loos - arXiv preprint arXiv:2403.09243, 2024 - arxiv.org
Data-based inference of directed interactions in complex dynamical systems is a problem
common to many disciplines of science. In this work, we study networks of spatially separate …

Non-reciprocal alignment induces asymmetric clustering in active repulsive mixtures

KL Kreienkamp, SHL Klapp - arXiv preprint arXiv:2403.19291, 2024 - arxiv.org
Heterogeneity is a ubiquitous feature in many biological and synthetic active matter systems
that are inherently out of equilibrium. In addition to conservative interactions between active …
