Time-Symmetry of Lagrangian Coherent Structures in Active Turbulence
Suvarchalanjan Bellaganti, Amal Manoharan, Kirti Kashyap +1
Active flows are central to mixing and transport across living systems. While Newtonian fluids remain laminar, diffusive and predictable at the microscale, living fluids like dense…
