Bose-Einstein Condensation is a state of matter that occurs at extremely low temperatures, close to absolute zero. In this state, a group of bosons, which are a type of particle, occupy the same quantum state, allowing them to behave as a single quantum entity. This phenomenon was first predicted by Satyendra Nath Bose and Albert Einstein in the early 20th century. When cooled to these temperatures, the particles lose their individual identities and exhibit unique properties, such as superfluidity. Bose-Einstein Condensates have been created in laboratories using atoms like rubidium and sodium, providing insights into quantum mechanics and the behavior of matter.
