The full form of BEC is Bose-Einstein Condensate. It represents a state of matter achieved when a sparse gas of bosons is cooled to temperatures near absolute zero. Interestingly, this unique state of matter can be found in materials like superfluids and superconductors
Scientists have explored Bose-Einstein Condensate as a valuable quantum simulator that aids in studying particles challenging to directly observe or create.
The word condensate in the full form of BEC is pretty similar to the concept of condensation. When a gas is cooled down, its particles start to lose energy and stick together. In other words, they condense into a liquid state. You might have observed this with water vapor changing into liquid upon cooling. This is exactly what happens with the BEC but with super-low temperatures.

History of BEC
The BEC or Bose-Einstein Condensate was predicted by Satyendra Bose and Albert Einstein. Based on their calculations to find the fifth state of matter, when some identical Bose particles approach each other and move slowly and closely, they will consequently convert to the lowest energy state which is the BEC. This is because when atoms are chilled to very low temperatures, their wavelike nature helps them to spread out and overlap. If the density is high enough and the temperature low, the atoms will be in a coherent state and form a single super-atom.

Characteristics of Bosons
Here are a few noteworthy characteristics of Bosons
- Bosons have integral spin numbers (0, 1, 2).
- They do not adhere to the Pauli exclusion principle.
- Bosons are constituted of more than one particle.
- They have nuclei with even mass numbers.
- Some bosons have the ability to carry force.
