# From Cosmology to Cold Atoms: Observation of Sakharov Oscillations in a Quenched Atomic Superfluid

@article{Hung2013FromCT, title={From Cosmology to Cold Atoms: Observation of Sakharov Oscillations in a Quenched Atomic Superfluid}, author={Chen-Lung Hung and Victor Gurarie and Cheng Chin}, journal={Science}, year={2013}, volume={341}, pages={1213 - 1215} }

Tinyverse Quantum many-systems, such superfluids, are difficult to study in equilibrium, and thus understanding their dynamics poses a particular challenge. When the strength of interactions was suddenly changed in a two-dimensional gas of cesium atoms, Hung et al. (p. 1213, published online 1 August; see the Perspective by Schmiedmayer and Berges) observed oscillations in the time and space domains analogous to the peaks in the spectrum of the cosmic microwave background. Abrupt interaction…

Observation of universal dynamics in a spinor Bose gas far from equilibrium

This work observes the emergence of universal dynamics far from equilibrium by evaluating spatially resolved spin correlations in a quasi-one-dimensional spinor Bose–Einstein condensate, and establishes an important class of non-stationary systems whose dynamics is encoded in time-independent scaling exponents and functions, signalling the existence ofnon-thermal fixed points.
