Who found out how to stop particles from moving when did they find out and what did they use to find out?

Researchers discovered how to stop particles from moving at absolute zero, which was theoretically proposed in the early 20th century. This concept was explored through experiments in cryogenics, where temperatures were lowered using methods like laser cooling and dilution refrigerators. Notably, in the 1990s, scientists achieved Bose-Einstein condensation, where atoms are cooled to near absolute zero, allowing them to occupy the same quantum state and effectively "stop" their movement.
