BOSE-EINSTEIN CONDENSATION: Enhanced: A New Trick of the Trade

n a Bose-Einstein condensate, all atoms share the same wave function. This can only be achieved at ultralow temperatures and, until recently, was only demonstrated for atoms in their atomic ground state. In his Perspective, Inguscio highlights the report by Robert et al., who have achieved a Bose-Einstein condensate of excited helium atoms. This opens up new avenues for investigating and using Bose-Einstein condensates.
