"Guiding Light Beams with a Trojan Approach via Lagrange Points"

Researchers at the University of Southern California have developed a novel method for trapping light waves by leveraging the unique properties of Lagrange points, which govern the orbits of celestial bodies like Trojan asteroids in the sun-Jupiter system. By creating a compact system in their laboratory that mimics the properties of Lagrange points, the researchers were able to guide and trap optical waves, similar to capturing Trojan asteroids within the sun-Jupiter orbit. This innovative approach could lead to the development of new techniques for guiding optical waves in unconventional environments and may have applications beyond optics, such as guiding acoustic waves or ultracold atoms.
