[OMC5-03] Visualizing three dimensional dynamics of quantized vortices in superfluid helium

*Yosuke Minowa¹, Yuki Yasui¹, Masaaki Ashida¹ (1. Osaka University)

We demonstrated the 3-dimensional visualization of quantized vortices in superfluid helium with silicon nanoparticles. Silicon nanoparticles were formed and dispersed in situ with pulsed laser ablation in the superfluid helium. By combining two images of an identical quantized vortex, each taken from a different direction, we reconstructed a three-dimensional structure of the quantized vortex.
