New ‘Superdiffusion’ Proof Probes the Mysterious Math of Turbulence

SMRTR summary

A team of mathematicians has proven that particles in a simplified turbulent fluid model exhibit "superdiffusion," spreading faster than expected due to energy transfer between vortices. This confirms a long-standing hypothesis and marks the first rigorous mathematical proof of this behavior. Using an advanced homogenization technique, the researchers provided new insights into turbulence's scattering effects and potentially opened avenues for further fluid dynamics research.
