How well can Diffusion Models learn Lagrangian-Tracer Statistics in Non-reciprocal Turbulence?
Pratyush Jha, Biswajit Maji, Rahul Pandit
Recent advances in generative artificial intelligence have led to significant potential applications in conventional fluid flows, including those that are turbulent. Can these meth…
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…
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…
