The article details the experimental creation of “solid light,” a novel state of matter where photons exhibit properties of both solid and fluid under extreme conditions. Researchers at Italy’s Institute of Nanotechnology of Lecce achieved this by directing a laser through a crystal, causing photons to interact with atoms and form polaritons—quasiparticles that behave as if they have mass. These polaritons self-organize into a crystalline lattice, creating a super-solid state that flows without friction while maintaining a rigid structure [1]. This state is described as “brighter than white” due to the precise alignment of photons, which enhances light emission efficiency [2].
The experiment required temperatures near absolute zero (approximately -273°C) to stabilize the quantum effects necessary for polariton formation. This condition mirrors the Bose-Einstein Condensate (BEC), a state of matter theorized by Einstein and Bose in the 1920s, where particles collapse into a single quantum state. However, unlike BEC, solid light involves photons interacting with matter to form a hybrid particle-matter system, enabling unique properties such as simultaneous rigidity and fluidity [3]. The study suggests that this state could provide insights into how light interacts with gravity, potentially challenging existing theories of relativity [4].
Technically, the process involves quantum entanglement between photons and atoms within the crystal, allowing the polaritons to maintain coherence at ultra-low temperatures. This breakthrough could advance quantum communication by enabling ultra-fast data transmission through entangled photon networks. Additionally, the super-solid state’s ability to conduct energy without resistance may inspire new materials for energy storage or optoelectronic devices [5]. The research underscores the potential of manipulating light at the quantum level to explore fundamental physics and develop transformative technologies.
