Stability and breakdown of chiral motion in non-reciprocal flocking
Aditya Kumar Dutta, Swarnajit Chatterjee, Matthieu Mangeat +1
We study a two-species Vicsek model with intra-species alignment and asymmetric inter-species couplings, where one species aligns with the other while the latter anti-aligns. Motiv…

Field-controlled interfacial transport and pinning in an active spin system
Mintu Karmakar, Matthieu Mangeat, Swarnajit Chatterjee +2
Field control provides a practical route to programmable active matter, yet how weak fields modify non-equilibrium coexistence and interfaces remains unclear. To address this, we s…
