Inverse energy transfer in three-dimensional quantum vortex flows
Piotr Z. Stasiak, Andrew Baggaley, Carlo. F. Barenghi +2
Vortex reconnections play a fundamental role in fluids.They increase the complexity of flow and develop small-scale motions.In this work, we report that in superfluids, they can al…

Experimental and theoretical evidence of universality in superfluid vortex reconnections
Piotr Z. Stasiak, Yiming Xing, Yousef Alihosseini +5
The minimum separation between reconnecting vortices in fluids and superfluids obeys a universal scaling law with respect to time. The pre-reconnection and the post-reconnection pr…

Cross-Component Energy Transfer in Superfluid Helium-4
Piotr Z. Stasiak, Andrew W. Baggaley, Giorgio Krstulovic +2
The reciprocal energy and enstrophy transfers between normal fluid and superfluid components dictate the overall dynamics of superfluid He including the generation, evolution a…
