Scientists observe quantum vortices in cold helium droplets
Helmholtz, Germany (SPX) Aug 27, 2014 - An international research team including DESY scientists has observed tiny quantum vortices in cold droplets of liquid helium. The team reports in the journal Science that the exotic vortices arrange themselves as densely packed lattices inside the nanodroplets. It is the first time that the quantum vortices, which have already been observed in larger samples of what is known as superfluid ... more
