A cloud of atoms with a temperature beyond absolute zero \u2013 which is also bizarrely hotter than any positive temperature imaginable \u2013 could be a mysterious new quantum state of matter.<\/p>\n

Luca Donini<\/a> at the University of Cambridge and his colleagues have put thousands of potassium atoms into this seemingly paradoxical situation by precisely manipulating their energy levels and quantum states. \u201cQuantum mechanics allows you to do this, while classical thermodynamics would never allow it,\u201d he says.<\/p>\n
