A Unified Wake Topology Map for He II Counterflow Past a Cylinder
Yingxuan Hu, Wenling Huang, Shihao Yang +3
Thermal counterflow of superfluid He past a cylinder produces quasi-steady eddies not only downstream but also anomalously upstream. However, the mechanism and organizing princ…

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…

Turbulent diffusion and dispersion in a superfluid
Yuan Tang, Sosuke Inui, Yiming Xing +2
Single-body diffusion and two-body dispersion are fundamental processes in classical turbulence, governing particle mixing and transport. However, their behaviors in superfluid tur…
