First observation of turbulence-like state in dense algal suspensions
Prince Vibek Baruah, Nadia Bihari Padhan, Biswajit Maji +2
Active turbulence arises typically in systems ranging from microorganisms and biopolymers to synthetic colloids, where chaotic flows are closely associated with motile topological…
Non-reciprocal Binary-fluid Turbulence
Biswajit Maji, Nadia Bihari Padhan, Axel Voigt +1
Although effective non-reciprocal interactions have been investigated in a variety of fields, their consequences have not been explored in hydrodynamical turbulence. We initiate su…
Vortex triplets, symmetry breaking, and emergent nonequilibrium plastic crystals in an active-spinner fluid
Biswajit Maji, Nadia Bihari Padhan, Rahul Pandit
The formation of patterns and exotic nonequilibrium steady states in active-fluid systems continues to pose challenging problems -- theoretical, numerical, and experimental -- for…
Emergent turbulence and coarsening arrest in active-spinner fluids
Biswajit Maji, Nadia Bihari Padhan, Rahul Pandit
We uncover activity-driven crossover from phase separation to a new turbulent state in a two-dimensional system of counter-rotating spinners. We study the statistical properties of…
