Phase separation, morphology, and metastability in the three-dimensional active Potts model
Aditya Kumar Dutta, Raja Paul
We study the three-dimensional active Potts model (APM) on a cubic lattice with 2, 4, and 6 orientational states. The steady-state phase diagrams exhibit low-density gaseous, high-…
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…
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…
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…
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…
