Solution
BEC means Bose–Einstein condensate.
A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero. Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which point microscopic quantum phenomena, particularly wavefunction interference, become apparent. A BEC is formed by cooling a gas of extremely low density, about one-hundred-thousandth the density of normal air, to ultra-low temperatures.
This state was first predicted, generally, in 1924–25 by Satyendra Nath Bose and Albert Einstein.
There are many well known examples of a Bose Einstein condensate. The most common is probably a condensate of photons known as a laser. There is the superfluid state of the helium-4 isotope and the standard type-I superconductor comprising a condensate of paired electrons, known as Cooper pairs.
At temperatures close to absolute zero, atoms can start to form a collective state known as a Bose–Einstein condensate (BEC). Scientists have found that this state of matter is useful as a 'quantum simulator' for investigating particles that have been predicted to exist by theory but are too difficult to create or observe directly.
As temper should be made to zero kelvin for obtaining BEC state which is not possible practically, its very difficult to obtain this state of matter.
