Abstract

We demonstrated the visualization of quantized vortices in superfluid helium with silicon nanoparticles. Nanoparticles were produced in situ with pulsed laser ablation and dispersed within the superfluid helium. The dispersed nanoparticles were utilized to decorate the quantized vortices, allowing for the imaging and visualization of the dynamics of the vortices, such as vortex reconnection.
