Sentences with phrase «ultracold atoms»

"Ultracold atoms" refers to atoms that have been cooled to extremely low temperatures, close to absolute zero. This process leads to unique behaviors of the atoms, allowing scientists to study and understand the fundamental properties and behaviors of matter at the atomic level. Full definition
