The same team demonstrated in 2017 the first creation of a Bose–Einstein condensate in space [70] and it is also the subject of two upcoming experiments on the International Space Station. [71] [72] Researchers in the new field of atomtronics use the properties of Bose–Einstein condensates in the emerging quantum technology of matter-wave ...
The thermodynamics of an ideal Bose gas is best calculated using the grand canonical ensemble.The grand potential for a Bose gas is given by: = = (). where each term in the sum corresponds to a particular single-particle energy level ε i; g i is the number of states with energy ε i; z is the absolute activity (or "fugacity"), which may also be expressed in terms of the chemical ...
Both Fermi–Dirac and Bose–Einstein become Maxwell–Boltzmann statistics at high temperature or at low concentration. Bose–Einstein statistics was introduced for photons in 1924 by Bose and generalized to atoms by Einstein in 1924–25. The expected number of particles in an energy state i for Bose–Einstein statistics is:
Fermionic condensate: Similar to the Bose-Einstein condensate but composed of fermions, also known as Fermi-Dirac condensate. The Pauli exclusion principle prevents fermions from entering the same quantum state, but a pair of fermions can be bound to each other and behave like a boson, and two or more such pairs can occupy quantum states of a ...
In the gas phase, the Bose–Einstein condensate remained an unverified theoretical prediction for many years. In 1995, the research groups of Eric Cornell and Carl Wieman, of JILA at the University of Colorado at Boulder, produced the first such condensate experimentally. A Bose–Einstein condensate is "colder" than a solid.
Bose–Einstein may refer to: Bose–Einstein condensate, a phase of matter in quantum mechanics Bose–Einstein condensation (network theory), the application of this model in network theory; Bose–Einstein condensation of polaritons; Bose–Einstein condensation of quasiparticles; Bose–Einstein correlations; Bose–Einstein integral

Besides these practical applications of Bose–Einstein correlations in interferometry, the quantum statistical approach [10] has led to quite an unexpected heuristic application, related to the principle of identical particles, the fundamental starting point of Bose–Einstein correlations.
