Cascades and transitions in turbulent flows
A Alexakis, L Biferale - Physics Reports, 2018 - Elsevier
Turbulent flows are characterized by the non-linear cascades of energy and other inviscid
invariants across a huge range of scales, from where they are injected to where they are …

Helicity, topology, and Kelvin waves in reconnecting quantum knots
Helicity is a topological invariant that measures the linkage and knottedness of lines, tubes,
and ribbons. As such, it has found myriads of applications in astrophysics, fluid dynamics …
