What is Bose Einstein condensate in simple words?
Bose–Einstein condensate (BEC) is what happens to a dilute gas when it is made very cold, near absolute zero (0 K which equals −273.15 °C or −459.67 °F). It forms when the particles that make it up have very low energy. A Bose–Einstein condensate is a change of state.
Where would you find Bose Einstein condensate?
In July 2018, an experiment aboard the International Space Station cooled a cloud of rubidium atoms to ten-millionth of a degree above absolute zero, producing a Bose-Einstein condensate in space.
How is Bose Einstein condensate used?
One application for BEC is for the building of so-called atom lasers, which could have applications ranging from atomic-scale lithography to measurement and detection of gravitational fields. It has alternatively been described as “as a superatom, where all the atoms share the same quantum mechanical state.”
How does BEC look like?
It looks like a dense little lump in the bottom of the magnetic trap/bowl; kind of like a drop of water condensing out of damp air onto a cold bowl. When it first forms, though, the condensate is still surrounded by the normal gas atoms, so it looks a bit like a pit inside a cherry.
Is laser An example of Bose-Einstein condensate?
The first Bose–Einstein condensate (BEC) to be cooled using just lasers has been made by a team in Austria. The process is much simpler, faster and more efficient than previous methods, which involve an extra stage of evaporative cooling.
Is condensate real?
Most relevant was the fact that Bose–Einstein condensate is human-made; it does not naturally occur. There’s a bit of subtext regarding the Spectrals that called for a man-made substance.
Does Bose-Einstein condensate exist in nature?
They’re not found naturally on Earth, but some speculate that the high-pressure conditions around neutron stars may give rise to BEC-like gases (1). High densities in that extreme environment may bring the particles so close together they act like condensates.
Can water be a Bose-Einstein condensate?
Superheated Bose-Einstein condensate exists above critical temperature. As the physicists explain, a superheated BEC is reminiscent of superheated distilled water (water that has had many of its impurities removed), which remains liquid above 100 °C, the temperature at which it would normally boil into a gas.
What is Einstein condensate?
Written By: Bose-Einstein condensate (BEC), a state of matter in which separate atoms or subatomic particles, cooled to near absolute zero (0 K, − 273.15 °C, or − 459.67 °F; K = kelvin), coalesce into a single quantum mechanical entity—that is, one that can be described by a wave function—on a near-macroscopic scale.
What state of matter is Bose Einstein?
A Bose–Einstein condensate ( BEC) is a state of matter of a dilute gas of low densities called bosons cooled to temperatures very close to absolute zero (-273.15 °C). Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which point microscopic quantum phenomena,…
Who is Bose Einstein?
Bose-Einstein condensates were first predicted theoretically by Satyendra Nath Bose (1894-1974), an Indian physicist who also discovered the subatomic particle named for him, the boson. Bose was working on statistical problems in quantum mechanics, and sent his ideas to Albert Einstein. Einstein thought them important enough to get them published.
