Growth of small localized perturbations in Surface Quasi-Geostrophic turbulence
V. J. Valadão, M. Cencini, F. De Lillo +2
The ``butterfly effect'', i.e. the growth of a localized infinitesimal perturbation, is the fundamental property of chaotic systems. While the butterfly effect is today an obvious…
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…
Inferring the Turbulent Breakup of Colloidal Aggregates Using Graph Neural Networks
Michele Buzzicotti, Massimo Cencini, Giulio Cimini +2
Solid aggregates in turbulent suspensions may break under the action of shear stresses. We explore the use of Graph Neural Networks (GNN) to infer aggregate fragmentation once the…
Defects, parcellation, and renormalized negative diffusivities in non-homogeneous oscillatory media
Marie Sellier-Prono, Massimo Cencini, David Kleinfeld +1
Spatial non-homogeneities can synchronize clusters of spatially-extended oscillators in different frequency plateaus. Motivated by physiological rhythms, we fully characterize the…
