TL;DR: In this article, the experimental observation of scaling in the time evolution following a sudden quench into the vicinity of a quantum critical point is reported. But the experimental system, a two-component Bose gas with coherent exchange between the constituents, allows for the necessary high level of control of parameters as well as the access to time-resolved spatial correlation functions.

TL;DR: In momentum space, this work reports the first observation of a frequency doubling in the quasicondensate regime, corresponding to a self-reflection mechanism due to the repulsive interactions, and gives insights into the dynamics of the breathing evolution.

TL;DR: It is shown experimentally that the bunching phenomenon, which manifests itself as super-Poissonian local fluctuations in momentum space, is present in all regimes and is in good agreement with ab initio calculations.

TL;DR: In this paper, the authors investigated the cooling produced by a loss process non selective in energy on a one-dimensional Bose gas with repulsive contact interactions in the quasi-condensate regime.

TL;DR: In this paper, the authors investigate the out-of-equilibrium dynamics following a sudden quench of the interaction strength, in a one-dimensional quasi-condensate trapped at the surface of an atom chip.
