Cold atom interferometry

Cold atom interferometry is a technique that uses extremely cold atoms—near absolute zero—to measure tiny forces, rotations, or changes in gravity. By cooling atoms with lasers, they move very slowly and behave like waves. These atomic waves are split, shifted, and recombined, creating interference patterns that reveal minute differences caused by external influences. This high precision makes cold atom interferometry valuable for advanced navigation, geophysical surveys, and fundamental physics research, offering unprecedented sensitivity compared to traditional sensors.
