Where would you find a Bose-Einstein condensate in a science lab?
Bose–Einstein condensate is made onboard the International Space Station. Looking to escape the clutches of gravity for as long as possible, physicists in the US have made a Bose–Einstein condensate onboard the International Space Station (ISS).
Is there Bose-Einstein condensation in 2D?
The physics of two-dimensional (2D) systems is profoundly different from our usual 3D experience. For a gas or fluid of identical bosons, this precludes Bose–Einstein condensation (BEC) in an infinite uniform 2D system. Nevertheless, a 2D Bose fluid can exhibit superfluidity below a finite critical temperature.
What is a Bose-Einstein condensate?
In this animation, Nobel laureate Eric Cornell describes the creation of a Bose-Einstein condensate. A gas of atoms is trapped and cooled by lasers. A magnetic trap then allows the hottest atoms to escape, resulting in a gas so cold and so dense that it coalesces into a “superatom”—the Bose-Einstein condensate.
What is the difference between the Bose-Einstein and Jin-DeMarco experiments?
While the Bose-Einstein experiments used one class of quantum particles known as bosons, Jin and DeMarco cooled atoms that are fermions, the other class of quantum particles found in nature. This was important to physicists because the basic building blocks of matter—electrons, protons and neutrons — are all fermions.
How cold can a condensate get?
The apparatus that made it is now at the Smithsonian Institution. The atoms within the condensate obey the laws of quantum physics and are as close to absolute zero—minus 273.15 Celsius or minus 459.67 degrees Fahrenheit—as the laws of physics will allow. The physicists likened it to an ice crystal forming in cold water.
When was the first condensation condensate made?
The condensation was first achieved at 10:54 a.m. on June 5, 1995, in a laboratory at JILA. The apparatus that made it is now at the Smithsonian Institution. The atoms within the condensate obey the laws of quantum physics and are as close to absolute zero—minus 273.15 Celsius or minus 459.67 degrees Fahrenheit—as the laws of physics will allow.
