The Life and Times. This form of matter was predicted in by Albert Einstein on the basis of the quantum formulations of the Indian physicist Satyendra Nath Bose. This section needs additional citations for verification. Our editors will review what you’ve submitted, and if it meets our criteria, we’ll add it to the article.

Bose–Einstein condensate

If the two states are equal in energy, each different configuration is equally likely. Yang showed that cold dark matter axions form a Bose-Einstein condensate by thermalisation because of gravitational self-interactions. As the density increases or the temperature decreases, the number of accessible states per particle becomes smaller, and at some point, more particles will be forced into a single state than the maximum allowed for that state by statistical weighting.

Retrieved 12 February Research was finally successful in hydrogen with the aid of the newly developed method of ‘evaporative cooling’. In the image accompanying this article, the velocity-distribution data indicates the formation of a Bose—Einstein condensate out of a gas of rubidium atoms. Retrieved 17 April Please note that our editors may make some formatting changes or correct spelling or grammatical einsteih, and may also contact you if any clarifications are needed.


Various isotopes have since been condensed. Bose—Einstein condensate is depicted as ghosts which was demystified as Bose—Einstein condensate in Netflix Originals Spectral.

InPyotr KapitsaJohn Allen and Don Misener discovered that helium-4 became a new kind of fluid, now known as a superfluidat temperatures less than condensads. Explicit use of et al. Quantum mechanics, science dealing with the behaviour of matter and light on the atomic and subatomic…. Retrieved 25 June BEC theory traces back towhen Bose considered how groups of photons behave.

The examples where this could happen are the Bose—Fermi composite condensates, [18] [19] [20] [21] effectively lower-dimensional condensates, [22] and dense condensates and superfluid clusters and droplets.

BEC research has yielded new atomic and optical physics, such as the atom laser Ketterle demonstrated in Superfluid helium has many unusual properties, including zero viscosity the ability to flow without dissipating energy and the existence of quantized vortices. The peak is not infinitely narrow because of the Heisenberg uncertainty principle: By construction, the GPE uses the following simplifications: Julian—Gregorian uncertainty CS1 maint: The reversible flip from attraction to repulsion stems from quantum interference among wave-like condensate atoms.

Superfluid helium-4 is a liquid rather than a gas, which means that the interactions between the atoms are relatively strong; the original theory of Bose—Einstein se must be heavily modified in order to describe it.

The Peletminskii equations are valid for any finite temperatures below the critical point.

Excitonselectron-hole pairs, were predicted to condense at low temperature and high density by Boer et al. Bose—Einstein condensation remains, however, fundamental to einztein superfluid properties of helium Magnetic ordering is the analog of superfluidity.

More tightly confined directions have bigger widths in the ballistic velocity distribution. Archived from the original on 24 October Many isotopes were soon condensed, then molecules, quasi-particles, and einstfin in The process of creation of molecular Bose condensate during the sweep of the magnetic field throughout the Feshbach resonance, as well as the reverse process, are described by the exactly solvable model that can explain many experimental observations.

The first molecular condensates were created in November by the groups of Rudolf Grimm at the University of InnsbruckDeborah Bowe. These manipulations hold promise for new types of light-based telecommunicationsoptical storage of data, and quantum computingthough the low-temperature requirements of BECs offer practical difficulties.
