BOSE-EINSTEIN CONDENSATE in particle physics and thermodynamics: state of matter that forms when a boson gas (one of the three basic types of elementary particles, along with quarks and leptons) cools near absolute zero (-273. 15 °C or 0 Kelvin). At such a very low temperature there is almost no movement and the atoms become a unique entity with quantum properties. Superfluidity and superconductivity are examples of condensate.
