Topological entropy of stationary three-dimensional turbulence
Ankan Biswas, Amal Manoharan, Ashwin Joy
Topological entropy serves as a viable candidate for quantifying mixing and complexity of a highly chaotic system. Particularly in turbulence, this is determined as the exponential…

Topological Entropy of Two Dimensional Turbulence
Amal Manoharan, Sai Subramanian, Ashwin Joy
Deformation of material lines drives transport and dissipation in many industrial and natural flows. Here we report an exact Eulerian formula for the stretching rate of a material…

Persistence in Active Turbulence
Amal Manoharan, Sanjay CP, Ashwin Joy
Active fluids such as bacterial swarms, self-propelled colloids, and cell tissues can all display complex spatio-temporal vortices that are reminiscent of inertial turbulence. This…
