The description of the new phase of matter bose einstein condensate bec

It is not applicable, for example, for the condensates of excitons, magnons and photons, where the critical temperature is comparable to room temperature. Numerical Solution The Gross-Pitaevskii equation is a partial differential equation in space and time variables. Usually it does not have analytic solution and different numerical methods, such as split-step Crank-Nicolson [12] and Fourier spectral [13] methods, are used for its solution.

Interesting facts you must know about her Bose-Einstein condensate We all know about matter and its three states and about plasma, the hot ionized gas considered as the fourth state, but we have seldom heard of something called as the fifth state of matter.

A Bose-Einstein condensate BEC is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero that is, very near 0 K or? Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which point macroscopic quantum phenomena become apparent.

Bose first sent a paper to Einstein on the quantum statistics of light quanta now called photons. Einstein was impressed, translated the paper himself from English to German and submitted it for Bose to the Zeitschrift fr Physik, which published it.

The Einstein manuscript,which was once assumed to be lost, was found in a library at Leiden University in Einstein proposed that cooling bosonic atoms to a very low temperature would cause them to fall or "condense" into the lowest accessible quantum state, resulting in a new form of matter.

It was Einstein who guessed that these same rules might apply to atoms. He worked out the theory for how atoms would behave in a gas if these new rules applied.

What he found was that the equations said that generally there would not be much difference, except at very low temperatures. If the atoms were cold enough, something very strange was supposed to happen.

It was so outlandish he was not sure it was correct. Do You Like This Story?Matter is the “stuff” of the universe. There are five known phases, or states, of matter: solids, liquids, gases, plasma and Bose-Einstein condensates. A Bose–Einstein condensate for a gas of rubidium atoms, confirming the discovery of a new phase of matter, the Bose–Einstein condensate.

Left: just before the appearance of a Bose–Einstein condensate. provides a relatively good description of the behavior of atomic BEC's. However.

Bose–Einstein condensate has been listed as a level-4 vital article in Science there is minor issue that the phrase "of dilute gas" right now suggests that BEC is a new gaseous phase of matter, when in reality BEC is not a gas but a different phase of matter and it just happens right now that technology used to make BEC starts with the. The Bose-Einstein state of matter was the only one created while your parents were alive. In , two scientists, Cornell and Weiman, finally created the condensate. When you hear the word condensate, think about condensation and the way gas molecules come together and condense and to a liquid. A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero. Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which point microscopic quantum phenomena, .

Velocity-distribution data (3 views) for a gas of rubidium atoms, confirming the discovery of a new phase of matter, the Bose–Einstein condensate. Left: just before the appearance of a Bose–Einstein condensate.

Center: just after the appearance of the condensate. Right: after further evaporation, leaving a sample of nearly pure condensate. Bose-Einstein condensate is a rare state (or phase) of matter in which a large percentage of bosons collapse into their lowest quantum state, allowing quantum effects .

New state of matter revealed: Bose-Einstein Condensate The matter surrounding us consists of atoms that obey the laws of quantum mechanics.

At normal temperatures these often agree with classical conceptions, and a gas under these conditions behaves rather like a swarm of billiard balls bouncing against one another and the containing walls.
