In a groundbreaking achievement, scientists have transformed light into a “super solid,” a state of matter that exhibits properties of both solids and liquids simultaneously. This development, realized by researchers in Italy, marks a significant milestone in quantum physics and opens new avenues for technological innovation.

The Science Behind Solid Light

Traditionally, photons – the elementary particles of light – do not interact with each other in a way that would allow them to form a solid structure. However, by using a semiconductor material and precise laser configurations, researchers have induced strong interactions between photons, leading to the formation of a supersolid state. Wikipedia

This supersolid state of light combines the rigidity of a solid with the frictionless flow of a superfluid, resulting in a material that maintains a crystalline structure while allowing particles to move without resistance. Such a state was previously theorized but had not been realized with light until now. Imperial College London+9The Brighter Side of News+9Reddit+9
