Cosmic inflation and Bose-Einstein condensates — •Ralf Schützhold — TU Dresden

Within our present standard model of cosmology, basically all inhomogeneities – including the seeds for the formation of structures such as our galaxy – originate from quantum fluctuations of the so-called inflaton field in the very early universe. The mechanism for the amplification of these quantum fluctuations can be reproduced for phonons within Bose-Einstein condensates under appropriate external conditions and could be measurable with present-day technology. This provides an opportunity to simulate exotic quantum effects of the very early universe in the laboratory.
