In a groundbreaking achievement, scientists from Italy have successfully transformed light into a supersolid, a unique state of matter that exhibits characteristics of both solids and liquids. Supersolids possess a crystalline structure while allowing for fluid-like flow, and this latest development could pave the way for advancements in quantum and photonic technologies. The research team, led by experts from the National Research Council (CNR), achieved this by coupling photons from a laser with a semiconductor material to create quasiparticles known as polaritons. By manipulating these polaritons, the researchers were able to induce a supersolid state, confirming its existence through intricate measurements. This milestone not only enhances our understanding of exotic matter states but also holds promise for future practical applications. The findings were published in the journal Nature.
