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…

Stability of discrete-symmetry flocks: sandwich state, traveling domains and motility-induced pinning

Swarnajit Chatterjee, Mintu Karmakar, Matthieu Mangeat +2

Polar flocks in discrete active systems are often assumed to be robust, yet recent studies reveal their fragility under both imposed and spontaneous fluctuations. Here, we revisit…

Flocking with random non-reciprocal interactions

Jiwon Choi, Jae Dong Noh, Heiko Rieger

Flocking is ubiquitous in nature and emerges due to short- or long-range alignment interactions among self-propelled agents. Two unfriendly species that antialign or even interact…

Stability of flocking in the reciprocal two-species Vicsek model: Effects of relative population, motility, and noise

Aditya Kumar Dutta, Matthieu Mangeat, Heiko Rieger +2

Natural flocks need to cope with various forms of heterogeneities, for instance, their composition, motility, interaction, or environmental factors. Here, we study the effects of s…

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

Matthieu Mangeat, Swarnajit Chatterjee, Jae Dong Noh +1

There is growing interest in multi-species active matter systems with reciprocal and non-reciprocal interactions. While such interactions have been explored in continuous symmetry…

Ordering kinetics in the active Ising model

Sayam Bandyopadhyay, Swarnajit Chatterjee, Aditya Kumar Dutta +3

We undertake a numerical study of the ordering kinetics in the two-dimensional () active Ising model (AIM), a discrete flocking model with a conserved density field coupled to…
