Laser Reveals Mysterious Order in Liquid Helium
An experiment at the Department of Energy’s SLAC National Accelerator Laboratory has revealed a well-organized 3-D grid of quantum “tornadoes” inside microscopic droplets of super-cooled liquid helium. This is 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. When chilled to extremes, liquid helium behaves according to the rules of quantum mechanics that apply to matter at the smallest scales and defy the laws of classical physics. This superfluid state is one of just a few examples of quantum behavior on a large scale that makes the behavior easier to see and study.
