Bose-Einstein condensate:

matter in the form of a gas of atoms, molecules, or elementary particles that have been so chilled that their motion is virtually halted and as a consequence they lose their separate identities and merge into a single entity.

"I would not say that the case is proven," he says, adding that the observed sound waves could have come from an artifact in the Bose-Einstein condensate. "But it is probably the closest anyone has come." In 1981, Unruh proposed creating black holes in the lab but wrote at the time that detecting Hawking radiation "is an extremely slim possibility."
To observe and test them in the lab, the researchers created a quantum system - a magnetic field of a cloud of rubidium atoms in a state of matter known as a Bose-Einstein condensate.
