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…

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…

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…
