Scientists successfully stir a supersolid for the first time, revealing its unique dual nature

Scientists have stirred a "supersolid" for the first time, demonstrating its unique properties as both a solid and a superfluid. This breakthrough provides direct evidence of the dual nature of this exotic state of matter. Previously, researchers could only observe the crystal structures of supersolids. The new study, published in *Nature*, shows how stirring the supersolid creates tiny whirlpools, known as quantized vortices, which are key indicators of superfluidity. The team used magnetic fields to stir the supersolid without damaging it. This advancement may help simulate extreme conditions found in neutron stars, where similar superfluid behavior is believed to occur.
