The study of soliton gases, large ensembles of interacting solitons, has received rapidly growing interest due to deep connections with other phenomena and various areas of physics. This Perspective reviews the main recent theoretical and experimental results in the field, and discusses various open questions and future challenges.

This is an investigation of collective motion of fish swimming in the presence of obstacles. The authors analyzed trajectories of zebrafish swimming in a tank with varying densities of pillars. As the density of pillars increased, the experiments exhibited a transition from mostly aligned fish, to fish oriented along the axes of the pillar lattice. The authors considered the relative orientations of two fish and developed a stochastic model, which qualitatively reproduced the experimental data.
