bose einstein 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 to be observed on a macroscopic scale. Einstein adopted the idea and extended it to atoms.

Sometimes referred to as the fifth state of matter a Bose-Einstein Condensate is a state of matter created when particles called bosons are cooled to near absolute zero -27315 degrees Celsius or -460 degrees Fahrenheit.

. Bose-Einstein condensate definition is - a state of matter that occurs when a set of atoms is cooled almost to absolute zero in which a statistical description of the positions of the atoms implies that they physically overlap each other and in effect form a single atom. A Bose-Einstein condensate is a group of atoms cooled to within a hair of absolute zero. A magnetic trap then allows the hottest atoms to escape resulting in a gas so cold and so dense that it coalesces into a superatomthe Bose-Einstein condensate. When you hear the word condensate think about condensation and the way gas molecules come together and condense and to a liquid.

BoseEinstein condensate BEC is what happens to a dilute gas when it is made very cold near absolute zero 0 K which equals 27315 C or 45967 F. The team led by Wieman and Cornell used laser and magnetic traps to create the Bose-Einstein condensate a tiny ball of rubidium atoms that are as stationary as the laws of quantum mechanics permit. When they reach that temperature the atoms are hardly moving relative to. At such low temperatures there is insufficient energy for the particles to move into positions that might cause their.

The Bose-Einstein state of matter was the only one created while your parents were alive. Bose-Einstein condensate BEC a state of matter in which separate atoms or subatomic particles cooled to near absolute zero 0 K 27315 C or 45967 F. In 1995 two scientists Cornell and Weiman finally created the condensate. A Bose-Einstein condensate BEC the first of which was shown experimentally 22 years ago isnt your garden variety state of matter.

K kelvin coalesce into a single quantum mechanical entitythat is one that can be described by a wave functionon a near-macroscopic scale. This led to the prediction of the existence of phenomena which became known as BoseEinstein condensate a dense collection of bosons which are particles with integer spin named after Bose which was demonstrated to exist by experiment in 1995. Wiemans technique cooled the atoms to about 10 millionths of a degree above absolute zero still far too hot to produce Bose-Einstein condensation. Matthew Schwartz Old Matthew Schwartz Created Date.

Once the atoms were trapped the researchers turned off the laser and kept the atoms in place by a magnetic field. 7 70 years after the Einstein prediction the BEC in weakly interacting Bose systems has been experimentally demonstrated - by laser coolingof a system of weakly- interacting alkali atoms in a magnetic trap. A gas of atoms is trapped and cooled by lasers. It forms when the.

It formed at a fraction above absolute zero and only in atoms that act like bosons one of two types of fundamental particles. About 10 million of these cold atoms were captured in the light trap. The condensate was formed inside a carrot-sized glass cell. In this animation Nobel laureate Eric Cornell describes the creation of a Bose-Einstein condensate.
