In a groundbreaking achievement, an international team of physicists has reported the successful change of laser light into a supersolid, a state of matter that is both solid and liquid. The findings, published in the scientific journal Nature on March 5, 2025, mark a meaningful advancement in our understanding of quantum mechanics and the behavior of matter at extreme conditions.
What is a Supersolid?
A supersolid is a bizarre state of matter defined by quantum mechanics. It exhibits properties of both a solid, where particles are arranged in a crystal-like structure, and a liquid, behaving like a fluid with no viscosity. Viscosity refers to internal friction within a substance, determining how smoothly it flows. Unlike ordinary solids,which remain stationary,a supersolid can flow,with its direction and density changing in response to particle interactions,all while maintaining its ordered lattice structure.
The creation of a supersolid typically requires extremely low temperatures, generally near absolute zero. At such low temperatures,the lowest energy state is achieved,eliminating the noise that heat introduces to particle interactions.This allows quantum mechanical effects to dominate the behavior of the material. The absence of viscosity is one such effect; all fluids, except superfluids and supersolids, possess some degree of viscosity.
Helium cooled to near absolute zero is a well-known example of a fluid without viscosity. This superfluid helium exhibits strange behaviors, such as climbing the walls of a glass and spilling out on its own due to the absence of friction.
From Light to Supersolid: A Novel Approach
While scientists have previously created supersolids using atomic gases, this new research employs a completely novel mechanism: creating a supersolid from light without using atoms.
The key to this achievement lies in quasiparticles called polaritons, which are formed by the coupling of light and matter. The research team began by precisely shaping gallium arsenide, a semiconductor, to create a special ridged structure that interacts with laser light.
When a laser is directed at the ridges of this gallium piece, the interaction between light and matter generates polaritons. The shape of the ridges restricts the movement of these polaritons, causing them to enter a supersolid state.In essence, light combines with matter and condenses into a supersolid.
Implications and Future Research
Supersolids are crucial for quantum mechanics research because they exhibit minute quantum interactions between particles regardless of temperature. Light-based supersolids, in particular, are more flexible and easier to handle than those made of atoms, possibly leading to a better understanding of the general properties of supersolids.
A deeper understanding of cryogenic materials and the quantum mechanical world could lead to applications in quantum computing, superconductors, and even zero-friction lubricants, among other possibilities.
The research team plans to continue investigating the structure of the newly created supersolid, focusing on its crystal structure.
Potential Applications of Supersolids

Laser Light Transformed into Supersolid: A Quantum Leap in Physics – Your Questions AnsweredRecent breakthroughs in physics have achieved the seemingly impossible: turning laser light into a supersolid. This Q&A article explores this fascinating development and its potential impact on future technologies. Frequently Asked Questions About light-Based SupersolidsQ: What is a supersolid?A: A supersolid is an exotic state of matter that exhibits properties of both a solid and a liquid simultaneously. It has a crystal-like structure (like a solid) but can also flow without viscosity (like a liquid). Essentially, it’s a material that can move freely while maintaining a rigid form. Q: How dose a supersolid differ from a regular solid or liquid?A: Unlike ordinary solids that remain stationary, a supersolid can flow. Unlike ordinary liquids, which have viscosity (internal friction), a supersolid flows without viscosity. It’s unique in that it possesses both long-range order (characteristic of solids) and the ability to flow without resistance (characteristic of superfluids, which are a special type of liquid). Q: How was a supersolid made from light?A: researchers used quasiparticles called polaritons, which are created by coupling light and matter. They precisely shaped gallium arsenide, a semiconductor, into a ridged structure.When laser light interacts with these ridges, polaritons are generated. The shape of the ridges restricts the polaritons’ movements, forcing them to enter a supersolid state.It’s, in essence, condensing light and matter into this unusual state. Q: What are polaritons?A: Polaritons are quasiparticles that arise from the strong coupling of electromagnetic waves (like light) with an excited dipole-carrying matter excitation (like those found in a semiconductor). They are neither purely light nor purely matter, but a hybrid of the two, inheriting properties from both. Q: Why is this research significant?A: This is a groundbreaking achievement because it demonstrates a novel way to create a supersolid, not from atoms, but from light. According to a Nature article published on March 5,2025,studying these light-based supersolids may provide a better understanding of the general properties of supersolids,especially because they are possibly more flexible and easier to handle than those made of atoms. This advancement paves the way for exploring the quantum world in new ways. Q: What are the potential applications of supersolids?A: A deeper understanding of supersolids and other cryogenic materials coudl lead to various applications. Some potential applications include:
Q: What are the next steps in this research?A: The research team plans to further investigate the structure of the light-based supersolid, specifically focusing on its crystal structure, to understand its properties and behavior in greater detail. This will help determine its full potential and how it can be utilized in future technologies. Q: Are supersolids stable at room temperature?A: No,typically,supersolids require extremely low temperatures,close to absolute zero,to form. At these temperatures, quantum mechanical effects dominate, allowing the supersolid state to emerge. Though, research continues to explore methods to create supersolids that are more stable at higher temperatures. |
