• Researchers at CNR-INO, CNR-Nanotec, and the University of Pavia have created the world’s first light-based supersolid.
• A supersolid behaves like both a solid (with crystalline structure) and a superfluid (allowing friction-free flow).
• The experiment involved semiconductor nanostructures manipulating light into a supersolid phase.
• This supersolid maintains a coherent quantum droplet structure while allowing free-flowing motion, unique to superfluids.
• The discovery challenges traditional views of light as pure energy, introducing light as a form of matter.
• The new supersolid may improve quantum computing by enhancing qubit stability in processors.
• In materials science, understanding supersolids could lead to the creation of high-performance materials.
• Light-based supersolids could revolutionize photonic energy storage technologies.
• This breakthrough could also pave the way for next-generation light-emitting devices and optical technologies.
• Experts like Iacopo Carusotto and Dimitrios Trypogeorgos highlight the novelty of this approach, marking a new phase in supersolidity research.
