Abstract
In this talk I will discuss first observations of vorticity in supefluid helium droplets. I will start with reviewing the basics of vorticity and previous theoretical works on vortices in He droplets. Then I will discuss experiments in large He droplets having diameter of 100 -1000 nm and the results of surface deposition experiments, which show vortex-catalyzed formation of elongated silver aggregates. Finally, the results of very recent experiments on X-ray diffraction imaging of the droplets at Stanford SLAC will be introduced. These indicate formation of Abrikosov vortex arrays as well as substantial shape deformations in the rotating superfluid droplets.
