X-ray laser probes tiny quantum tornadoes in superfluid droplets

An experiment at the Department of Energy's SLAC National Accelerator Laboratory revealed a well-organized 3-D grid of quantum 'tornadoes' inside microscopic droplets of supercooled liquid helium -- the first time this formation has been seen at such a tiny scale. The findings by an international research team provide new insight on the strange nanoscale traits of a so-called 'superfluid' state of liquid helium.
