In this context, this thesis presents an extensive experimental study of non-equilibrium dynamics in 1d Bose gases, with a focus on processes that go beyond simple dephasing dynamics. It reports on the observation of recurrences of coherence in the post-quench dynamics of a pair of 1d Bose gases and presents a detailed study of their decay. The latter represents the first observation of phonon-phonon scattering in these systems. Furthermore, the thesis investigates a novel cooling mechanism occurring in Bose gases subjected to a uniform loss of particles. Together, the results presented show a wide range of non-equilibrium phenomena occurring in 1d Bose gases and establish them as an ideal testbed for many-body physics beyond equilibrium.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Phase transformations (Statistical physics)Condensed materialsQuantum physicsLow temperature physicsLow temperaturesQuantum Gases and Condensateshttps://scigraph.springernature.com/ontologies/product-market-codes/P24033Quantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080Low Temperature Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P25130Phase transformations (Statistical physics).Condensed materials.Quantum physics.Low temperature physics.Low temperatures.Quantum Gases and Condensates.Quantum Physics.Low Temperature Physics.530.144530.144Rauer Bernhardauthttp://id.loc.gov/vocabulary/relators/aut1058786BOOK9910337879603321Non-Equilibrium Dynamics Beyond Dephasing2502496UNINA
