Lagrangian manifestation of anomalies in active turbulence
@article{Singh2021LagrangianMO, title={Lagrangian manifestation of anomalies in active turbulence}, author={Rahul K. Singh and Siddhartha Mukherjee and Samriddhi Sankar Ray}, journal={Physical Review Fluids}, year={2021} }
We show that Lagrangian measurements in active turbulence bear imprints of turbulent and anomalous streaky hydrodynamics leading to a self-selection of persistent trajectories— L´evy walks — over diffusive ones. This emergent dynamical heterogeneity results in a super-diffusive first passage distribution which could lead to biologically advantageous motility. We then go beyond single-particle statistics to show that for the pair-dispersion problem as well, active flows are at odds with inertial…

Pair dispersion and doubling time statistics in two-dimensional turbulence.
- PhysicsPhysical review letters
- 2005
Experimental measurements of pair separation statistics in two-dimensional turbulence are reported for an electromagnetically forced stratified-layer system with simultaneous ranges of direct-enstrophy and inverse-energy transfer separated by a well-defined spatial injection scale and it is shown how the measured scalings of the mean quantities are consistent with exponential behavior in the enstrophy range and power-lawbehavior in the inverse- energy range.
Meso-scale turbulence in living fluids

The authors' experimental results for the bacterial flow statistics agree well with predictions from a minimal model for self-propelled rods, suggesting that at high concentrations the collective motion of the bacteria is dominated by short-range interactions.
Anomalous Diffusion and Lévy Walks Distinguish Active from Inertial Turbulence.
- PhysicsPhysical review letters
- 2021
It is shown that such dense active suspensions manifest superdiffusion, via Lévy walks, which masquerades as a crossover from ballistic to diffusive scaling in measurements of mean-squared displacements, and is tied to the emergence of hitherto undetected oscillatory streaks in the flow.

By tracking trajectories of fluorescently labelled individuals within such dense swarms, it is found that the bacteria are performing super-diffusion, consistent with Lévy walks.
