Physicists Unveil Quantum Vortices in Supersolid Matter

Scientists at the University of Innsbruck have successfully stirred a supersolid, a state of matter that exhibits both solid and superfluid properties, providing direct evidence of its dual nature. This breakthrough, published in Nature, involved creating quantized vortices, which are indicative of superfluidity, by using magnetic fields to rotate the supersolid. The research could help simulate extreme phenomena like those in neutron stars, where superfluid vortices are believed to cause rotational speed changes.
