Exploration of magnon Bose–Einstein condensate (BEC) may enable intriguing applications in magnonic devices. Here the authors show experimentally the condensed magnons forming compact humps of BEC density can propagate many hundreds of micrometers in the form of Bogoliubov waves. Dmytro A. Bozhko , ...
In 1938 London ( 1938 ) introduced the concept of macroscopic occupation of the ground state and related it to the long range coherence properties of the Bose-Einstein condensate. Since that period, the physics of the phenomenon has become standard knowledge in statistical mechanics and present in...

The Bose-Einstein condensate (BEC) is one of the five primary states of matter. In it, atoms reach such low energies that the rules of quantum mechanics dictate that they stop acting as individual atoms and behave like a single "super atom." A Bose-Einstein condensate forms only when mater...

Define Bose-Einstein condensate. Bose-Einstein condensate synonyms, Bose-Einstein condensate pronunciation, Bose-Einstein condensate translation, English dictionary definition of Bose-Einstein condensate. n. A state of matter that forms below a critical
Bose–Einstein condensation (BEC) is a special many-boson phenomenon that was observed in atomic particles at ultra-low temperatures. Later, BEC was also shown for non-atomic bosons, such as photons. Those experiments were usually done in micron-size cavities, where the power (particle number)...
