Which gas is used in BEC?
On 5 June 1995, the first gaseous condensate was produced by Eric Cornell and Carl Wieman at the University of Colorado at Boulder NIST–JILA lab, in a gas of rubidium atoms cooled to 170 nanokelvins (nK). Shortly thereafter, Wolfgang Ketterle at MIT produced a Bose–Einstein Condensate in a gas of sodium atoms.
Is Bose-Einstein condensate a gas?
Researchers using a clever new magnetic trap have cooled a cloud of rubidium‐87 atoms to a record‐low 20 nanokelvins and achieved the Holy Grail of low‐temperature atomic physics: Bose–Einstein condensation in a gas.
What is BEC 5th state of matter?
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 (-273.15 degrees Celsius, or -460 degrees Fahrenheit).
Why is bec the fifth state of matter?
The fifth state of matter, known as a Bose-Einstein condensate (BEC), has been created in the microgravity of the International Space Station for the first time. This exotic and rare form of matter is only produced when a gas of boson-like particles is cooled to temperatures just above absolute zero (about -459.67F).
What is plasma and BEC?
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. They are a group of atoms cooled to within a hair of absolute zero.
Which scientist discovered the fifth state of matter?
Bose-Einstein Quantum “Fifth State Of Matter” Seen For 1st Time In Space.
What is the 4th and 5th state of matter?
The five phases of matter. There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates.
What are the properties of BEC?
The most obvious property of a BEC is that a large fraction of its particles occupy the same, namely the lowest, energy state. In atomic condensates this can be confirmed by measuring the velocity distribution of the atoms in the gas.
