Quantum vortex driven Kelvin wave in the thermal background of superfluid helium
Simone Scollo, Luca Galantucci, Giorgio Krstulovic
We present numerical evidence that Kelvin waves (KWs) on quantized vortices in superfluid helium can be directly observed in the normal fluid component at finite temperatures. Usin…

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…

Quantum vortices leave a macroscopic signature in the normal fluid
Luca Galantucci, Giorgio Krstulovic, Carlo F Barenghi
Recent work has highlighted the remarkable properties of quantum turbulence in superfluid helium II, consisting of a disordered tangle of quantised vortex lines which interact with…
