In a unique state of matter called a superfluid, tiny "tornadoes" form that may play an important role in nanotechnology, superconductivity, and other applications. Just as tornadoes are invisible air currents that become visible when they suck debris into their cores, the quantum vortices in superfluids attract atoms that make the vortices visible. Quantum vortices are so small they can only be imaged using very short-wavelength x-rays, however.
About ricomayroAndrey is a professor in the departments of Chemistry and Physics and Astronomy in the University of Southern California in Los Angeles. His research includes properties of superfluid helium nanodroplets and the characteristics of the atomic and molecular aggregates inside these droplets.
