Unlocking the Secrets of Light: From Einstein's Theories to Physics-Defying Quasiparticles

Scientists have manipulated light to behave as if influenced by gravity using distorted photonic crystals, opening up possibilities for advancements in optics and materials science. This breakthrough could also have implications for the development of 6G communication. By introducing lattice distortion to photonic crystals, researchers were able to manipulate the photonic band structure, resulting in a curved beam trajectory similar to light passing by a massive celestial body. The experiment successfully demonstrated the deflection of terahertz waves, showcasing the potential for in-plane beam steering within the terahertz range, which could be utilized in 6G communication.
