摘要：

Recent developments in simulating fundamental quantum field theoretical effects in the kinematical context of analogue gravity are reviewed. Specifically, it is argued that a curved spacetime generalization of the Unruh-Davies effect - the Gibbons-Hawking effect in the de Sitter spacetime of inflationary cosmological models - can be implemented and verified in an ultracold gas of bosonic atoms.
