Nonreciprocal Alignment Induces Asymmetric Clustering in Active Mixtures

KL Kreienkamp, SHL Klapp - Physical Review Letters, 2024 - APS
Heterogeneity is ubiquitous in biological and synthetic active matter systems that are
inherently out of equilibrium. Typically, such active mixtures involve not only conservative …

Coexistence of uniform and oscillatory states resulting from nonreciprocity and conservation laws

D Greve, G Lovato, T Frohoff-Hülsmann, U Thiele - Physical Review Letters, 2025 - APS
Employing a two-species Cahn-Hilliard model with nonreciprocal interactions, we show that
the interplay of nonreciprocity and conservation laws results in the robust coexistence of …

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 …
