Flock and swarm models are mostly based on the alignment of the velocity vectors of animals (birds, fishes, bats, etc.), following the very successful Vicsek model. Here, we explore a simple alternative where the animal decides the sense of its movement based only on the number of neighbors and the weak dependence on a landmark. This defines a class of density-based interacting random walks which seems to describe qualitatively mosquito swarms. The model presents a phase transition-like behavior that seems to be interesting to apply to stationary swarms, in general.
期刊介绍:
The Brazilian Journal of Physics is a peer-reviewed international journal published by the Brazilian Physical Society (SBF). The journal publishes new and original research results from all areas of physics, obtained in Brazil and from anywhere else in the world. Contents include theoretical, practical and experimental papers as well as high-quality review papers. Submissions should follow the generally accepted structure for journal articles with basic elements: title, abstract, introduction, results, conclusions, and references.
