In inflationary cosmology, the rapid expansion of the early universe resulted in the spontaneous production of cosmological particles from vacuum fluctuations, observable today in the cosmic microwave background anisotropies. The analogue of cosmological particle creation in a quantum fluid could provide insight, but an observation has not yet been achieved. Here we report the spontaneous creation of analogue cosmological particles in the laboratory, using a quenched 3dimensional quantum fluid… Expand

From Cosmology to Cold Atoms: Observation of Sakharov Oscillations in a Quenched Atomic Superfluid
The observation of Sakharov oscillations in the density fluctuations of a quenched atomic superfluid is reported through a systematic study in both space and time domains and with tunable interaction strengths to suggest a different approach to the study of nonequilibrium dynamics of quantum many-body systems and the exploration of their analogs in cosmology and astrophysics.

Bose-Einstein condensates BEC’s have recently been the subject of considerable study as possible analog models of general relativity. In particular it was shown that the propagation of phase… Expand

Quantum turbulence in condensate collisions: an application of the classical field method.
The classical field method is applied to simulate the production of correlated atoms during the collision of two Bose-Einstein condensates, and quantum correlation functions for the scattered atoms show that the correlation between pairs of atoms of opposite momentum is rather small. Expand
Observation of the Bogoliubov Dispersion in a Fluid of Light.
This Letter proposes and implements a general method for measuring the excitations spectrum in a fluid of light, based on a group velocity measurement and observes a Bogoliubov-like dispersion with a speed of sound scaling as the square root of the fluid density. Expand
