Turbulence has associated chaotic features. In the past couple of decades, there has been
growing interest in the study of these features as an alternative means of understanding …

Active processes drive biological dynamics across various scales and include subcellular
cytoskeletal remodelling, tissue development in embryogenesis and the population-level …

Fully developed turbulence is a universal and scale-invariant chaotic state characterized by
an energy cascade from large to small scales at which the cascade is eventually arrested by …

We demonstrate that the complex spatiotemporal structure in active fluids can feature
characteristics of hyperuniformity. Using a hydrodynamic model, we show that the transition …

Collective phenomena arise from interactions within complex systems, leading to behaviors
absent in individual components. Observing quantum collective phenomena with …

The need for structuring on micrometer scales is abundant, for example, in view of phononic
applications. We here outline a novel approach based on the phenomenon of active …

In the domain growth process, small structures gradually vanish, leaving behind larger ones.
We investigate spectral energy transfers in two standard models for domain growth:(a) the …

We study two models of overdamped self-propelled disks in two dimensions, with and
without aligning interactions. Both models support active mesoscale flows, leading to chaotic …

We uncover a new type of turbulence–activity-induced homogeneous and isotropic
turbulence–in a model that has been employed to investigate motility-induced phase …

Bacterial suspensions and other active fluids can develop highly dynamical vortex states
called mesoscale turbulence. Here, we reveal the pronounced effect of non-Newtonian …
