We detail the experimental observation of the non-equilibrium many-body phenomenon prethermalization. We study the dynamics of a rapidly and coherently split one-dimensional Bose gas. An analysis based on the use of full quantum mechanical probability distributions of matter wave interference contrast reveals that the system evolves towards a quasi-steady state. This state, which can be characterized by an effective temperature, is not the final thermal equilibrium state. We compare the…

Relaxation and Prethermalization in One-Dimensional Bose Gases
The study of relaxation processes remains a challenge despite considerable theoretical and experimental efforts. In this chapter, we study such processes using a 1D Bose gas. The system is quenched…

Prethermalization at Low Temperature: The Scent of Long-Range Order.
TLDR
It is shown that the prethermal quasistationary state can be approximated by a mixed state that violates cluster decomposition property, and that the transverse-field Ising chain, where the full-time evolution is computed analytically, and the (nonintegrable) anisotropic next-nearest-neighbor Ising model, which is investigated numerically.

We propose a new type of experimentally feasible quantum quench protocol in which a quantum system is prepared in a coherent, localized excited state of a Hamiltonian. During the evolution of this…

Quench dynamics and nonequilibrium phase diagram of the bose-hubbard model.
TLDR
The existence of two distinct nonequilibrium regimes is surprising given the nonintegrability of the Bose-Hubbard model and this phenomenon is related to the role of quasiparticle interactions in the Mott insulator.

Thermalization after an interaction quench in the Hubbard model.
TLDR
This work uses nonequilibrium dynamical mean-field theory to study the time evolution of the fermionic Hubbard model after an interaction quench and indicates a dynamical phase transition which should be observable in experiments on trapped fermionics atoms.
Intrinsic dephasing in one-dimensional ultracold atom interferometers
TLDR
It is shown that the phase coherence between the condensates decays exponentially with a dephasing time that depends on intrinsic parameters: the interaction strength, sound velocity, and density, and Interestingly, significant temperature dependence appears only above a cross-over scale T∗.
