What is the Bose-Einstein state?
What is the Bose-Einstein state?
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.
Are all Bose-Einstein condensates Superfluids?
Superfluidity of Bose-Einstein condensates in ultracold atomic gases. The BEC systems considered include a uniform superfluid in free space, a superfluid with its density periodically modulated, a superfluid with artificially engineered spin-orbit coupling, and a superfluid of pure spin current.
Did Bose-Einstein condensates form absolute zero?
A Bose-Einstein condensate (BEC), the first of which was shown experimentally 22 years ago, isn’t your garden variety state of matter. It formed at a fraction above absolute zero and only in atoms that act like bosons, one of two types of fundamental particles.
What is the 6th state of matter?
The fermionic condensate is a cloud of cold potassium atoms forced into a state where they behave strangely. The new matter is the sixth known form of matter after solids, liquids, gases, plasma and a Bose-Einstein condensate, created only in 1995.
Who discovered the Bose-Einstein condensate?
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.
What are the 21 states of matter?
Bose–Einstein condensate.
What is plasma and BEC?
Plasma and Bose-Einstein condensate are fourth and fifth states of matter respectively. Plasma: It may not be seen widely in the earth but it is to believe that in the universe everything is made up of plasma. Bose-Einstein Condensate (BEC): They are considered as the fifth states of matter after the plasma.
