Nikolay Bogoliubov considered perturbations on the limit of dilute gas,  finding a finite pressure at zero temperature and positive chemical potential.
Superconductivity as Bose-Einstein condensation|INIS
Kishor Kumar; et al. The phenomena of superfluidity of a Bose gas and superconductivity of a strongly-correlated Fermi gas a gas of Cooper pairs are tightly connected to Bose—Einstein condensation.
Most likely they formed molecules of two rubidium atoms;  energy gained by this bond imparts velocity sufficient to leave the trap without being detected. The Harvard University Gazette. Weiss 12 February 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.
In condensation was demonstrated in antiferromagnetic Tl Cu Cl 3 at temperatures as large as 14 K.
Bose—Einstein condensation remains, however, fundamental to the superfluid properties of helium From Wikipedia, the free encyclopedia.
With an additional step called evaporative cooling, the temperature is then further lowered to less than a millionth of a degree above zero, at which point the atoms almost come to a standstill.
Retrieved 26 October The particles lose their individual nature and behave like one giant super-particle—the Bose—Einstein condensate. Archived from the original on 12 October Years after, inKirkpatrick and Dorfman obtained similar equations using another microscopical approach.
The first demonstration of a BEC in weightlessness was achieved in at a drop tower in Bremen, Germany by a consortium of researchers led by Ernst M. The Peletminskii equations also reproduce Khalatnikov hydrodynamical equations for superfluid as a limiting case.
These topological objects feature a phase gradient across their nodal plane, which stabilizes their shape even in propagation and interaction. This article, as you might’ve gathered, completely spoils most of the story of Spectral. Jin quickly went on to create the first fermionic condensate composed of Cooper pairs.
Examples include experiments that have demonstrated interference between condensates due to wave—particle duality the study of superfluidity and quantized vorticesthe creation of bright matter wave solitons from Bose condensates confined to one dimension, and the slowing of light pulses to very low speeds using electromagnetically induced transparency.
Retrieved 12 February The Peletminskii equations are valid for any finite temperatures below the critical point.
 Realization of a sonic black hole analogue in a Bose-Einstein condensate
Steven Chu was a co-inventor. They cooled a dilute vapor of approximately two thousand rubidium atoms to below nK using a combination of laser cooling a technique that won its inventors Steven ChuClaude Cohen-Tannoudjiand William D.
Retrieved 26 January Magnetic ordering is the analog of superfluidity. JETP 7, ]; ibid. The original interacting system can be converted to a system of non-interacting particles with a dispersion law.
Julian—Gregorian uncertainty CS1 maint: Various isotopes have since been condensed. If the number of particles is less than the number of thermally accessible states, for high temperatures and low densities, the particles will all be in different states.
But it took a long time to develop the necessary experimental techniques and find suitable materials to actually create it, which finally happened in So a collection of enough Bose particles in thermal equilibrium will mostly be in the ground state, with only a few in any excited state, no matter how small the energy difference.
Bose—Einstein condensation of quasiparticles. Fast optical exciton creation was used to form condensates in sub-kelvin Cu 2 O in on.
InPyotr KapitsaJohn Allen and Don Misener discovered that helium-4 became a new kind of fluid, now known as a superfluidat temperatures less than 2. This section needs additional citations for verification. If you haven’t seen it yet, it should be on Netflix in your country.
Bose—Einstein condensation also applies to quasiparticles in solids. A BEC is formed by cooling a gas of extremely low density, about one-hundred-thousandth the density of normal airto ultra-low temperatures.

Ketterle’s condensate had a hundred times more atoms, allowing important results such as the observation of quantum mechanical interference between two different condensates. IBM This intriguing phenomenon—sometimes called the fifth state of matter next to solid, liquid, gas and plasma—was predicted by Satyendra Nath Bose and Albert Einstein in the s.
