Researchers have achieved a groundbreaking feat by transforming light into a quantum crystalline structure, creating a “supersolid” that is both solid and liquid at the same time. This innovation marks a significant step forward in condensed-matter physics.
A supersolid is a state of matter characterized by particles condensing into an orderly, crystalline solid while exhibiting properties similar to a liquid with no viscosity. Typically, solids do not move on their own; however, supersolids can change direction and density depending on particle interactions while maintaining an organized lattice structure.
The creation of a supersolid from light requires extremely low temperatures, typically near absolute zero (-459.67°F or -273.15°C). At these temperatures, particles interact with each other based solely on quantum mechanics, rather than heat, which enables scientists to study the behavior and characteristics of supersolids in unprecedented detail.
This new development is particularly exciting because it opens up possibilities for studying condensed-matter physics without the influence of temperature. By mapping out the properties of supersolids, researchers can gain insights into how atoms and particles interact, shedding light on fundamental principles of the world we live in.
The creation of a supersolid from light has far-reaching implications, including potential applications in quantum computing, superconductors, frictionless lubricants, and other fields. This breakthrough marks an exciting step forward in understanding the behavior of matter at its most fundamental level.
