Sisyphus cooling

Sisyphus cooling is an advanced method used to reduce the temperature of atoms or molecules by using carefully timed laser light. The laser interacts with the particles, causing them to lose kinetic energy, which lowers their temperature. This process is similar to pushing a ball uphill repeatedly—like Sisyphus from mythology—where energy is continuously removed from the system. By precisely controlling the laser's frequency and timing, scientists can cool particles to near absolute zero, enabling precise experiments in quantum physics and atomic research.
