Bose–Einstein condensates (BECs) are a type of quantum material and a state of matter.
A Bose-Einstein condensate is a group of atoms cooled close to absolute zero. When they reach that temperature the atoms are hardly moving relative to each other; they have almost no free energy to do so. At that point, the atoms begin to clump together, and enter the same energy states. They become identical, from a physical point of view, and the whole group starts behaving as though it were a single atom.
