The first atomistic simulations that reveal the mechanism of Rayleigh fission are presented. It
is demonstrated that simple ion or macroion ejection takes place through droplet …

Ultrasound in bulk liquid and superfluid helium has been used for multiple studies, including
generation of quantum turbulence, and inducing homogenous or heterogenous cavitation …

We demonstrate an experimental setup to trap multielectron bubbles in bulk liquid He 4
using a point Paul trap. The experimental configuration is based on dc and rf electric fields …
