Specifically, it is argued that a curved space-time generalization of the Unruh-Davies effect -- the Gibbons-Hawking effect in the de Sitter space-time of inflationary cosmological models -- can be implemented and verified in an ultracold gas of bosonic atoms.23 pages, 2 figures; invited brief review for Modern Physics Letters A, as publishedOther Condensed MatterGeneral Relativity and Quantum CosmologyHigh Energy Physics - TheoryQuantum Physicstext
