Extensive Spatio-Temporal Chaos in Non-reciprocal Flocking
Chul-Ung Woo, Jae Dong Noh, Heiko Rieger
Non-reciprocal interactions in active matter give rise to a multitude of fascinating phenomena among which are collective oscillatory states without intrinsic particle chirality an…
Nonreciprocal yet Symmetric Multi-Species Active Matter: Emergence of Chirality and Species Separation
Chul-Ung Woo, Heiko Rieger, Jae Dong Noh
Nonreciprocal active matter systems typically feature an asymmetric role among interacting agents, such as a pursuer-evader relationship. We propose a multi-species nonreciprocal a…
Collective behavior in the nonreciprocal multi-species Vicsek model
Chul-Ung Woo, Heiko Rieger, Jae Dong Noh
We investigate collective behavior in a -species Vicsek model with a nonreciprocal velocity alignment interaction. This system is characterized by a constant phase shift in…
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…
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…
Motility-Induced Pinning in Flocking System with Discrete Symmetry
Chul-Ung Woo, Jae Dong Noh
We report a motility-induced pinning transition in the active Ising model for a self-propelled particle system with discrete symmetry. This model was known to exhibit a liquid-gas…
