Question

Where is BEC found?

Answer 1

Two examples of materials containing Bose-Einstein condensates are superconductors and superfluids. Superconductors conduct electricity with virtually zero electrical resistance: Once a current is started, it flows indefinitely. The liquid in a superfluid also flows forever. In effect, there is no friction. The nucleons in a neutron star⁹ are believed to form a superfluid. Scientists have been able to make superfluids in the laboratory by cooling materials to very low temperatures. Helium-4 below a temperature of 2.17 Kelvins is an example.
