Statistical orientation and distribution of columnar ice crystals in turbulent flows
A. Pumir, M. Z. Sheikh, K. Gustavsson +3
We study the motion of columnar ice crystals that form in clouds over a range of low temperature. Our focus here is on elongated ice crystals, which are smaller than the size of th…

Adaptive shape control for microswimmer navigation in turbulence
Jingran Qiu, Lorenzo Piro, Luca Biferale +3
Navigation in turbulent environments is a fundamental challenge for biological and artificial microswimmers. While most existing studies focus on adapting motility or steering, the…

Short term vs. long term: optimization of microswimmer navigation on different time horizons
Navid Mousavi, Jingran Qiu, Lihao Zhao +2
We use reinforcement learning to find strategies that allow microswimmers in turbulence to avoid regions of large strain. This question is motivated by the hypothesis that swimming…
