A supersolid is matter that is both crystalline and fluid. It is created from atoms cooled almost to absolute zero. In new work, physicists obtained such a substance as a triangular lattice of droplets. Each droplet oscillates in its own rhythm. When the rhythms of neighboring droplets slightly diverge, a quantum vortex is born in the gaps between them, like a dancer stepping into a gap in a round dance. Slow divergences give birth to vortices at the corners, and when the rhythms speed up and synchronize, the vortices come into ordered motion, colliding and vanishing. Similar to a pulsar with its strict pulses, the phase rhythm dictates the appearance of vortices. Remarkably, just three droplets are enough — the minimal ensemble for a quantum dance. The effect, predicted by Landau for superfluids, gains new life here. In the future, such rhythm control will pave the way for controlling quantum systems.
