Here is the latest research showing PHOTON IN A SOLID STATE. FREEZING LIGHT AS SOLID
Italian scientists ‘freeze’ light, unlocking a new quantum mystery—Here’s what it means Italian scientists have achieved a groundbreaking feat by "freezing" light, demonstrating that it can behave as a super solid, a state of matter that combines rigidity and quiddity, with Signiant implications for quantum computing and technology. Italian scientists ‘freeze’ light, unlocking a new quantum mystery—Here’s what it means Italian scientists have achieved a surprising feat—freezing light. The discovery, recently published in Nature, shows that light can behave as a super solid, a state of matter that owes without friction while maintaining a solid-like structure. Researchers Antonio Gian fate from CNR Nanotec and Davide Nigro from the University of Pavia led the study. They described the findings as "just the beginning" of understanding super solidity in light. A super solid is a rare state of matter where particles are both rigid and fluid-like. Until now, it had only been observed in Bose-Einstein condensates (BEC), which form at temperatures near absolute zero. By manipulating photons under controlled quantum conditions, the scientists demonstrated that light, too, can exhibit this behaviour. How Scientists ‘Froze’ Light in the Lab Freezing usually involves lowering a liquid’s temperature until it becomes solid. However, the researchers took a different approach, creating a super solid state in light using advanced quantum techniques. They worked with a semiconductor platform where photons, the fundamental particles of light, behaved similarly to electrons. Using a gallium arsenide structure with microscopic ridges, they red a laser to generate hybrid light matter particles called polaritons. As the number of photons increased, they formed a pattern known as satellite condensates. These condensates had the same energy but opposite wavenumbers, leading to a Italian scientists ‘freeze’ light, unlocking a new quantum mystery.
