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
Hierarchical relaxation dynamics in a tilted two-band Bose-Hubbard model
We numerically examine slow and hierarchical relaxation dynamics of interacting bosons described by a tilted two-band Bose-Hubbard model. The system is found to exhibit signatures of quantum chaos
Prethermalization and universal dynamics in near-integrable quantum systems
We review the recent progress in the understanding of the relaxation of isolated near-integrable quantum many-body systems. Focusing on prethermalization and universal dynamics following a quench, we
Prethermalization at Low Temperature: The Scent of Long-Range Order.
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.

In this work we consider the dynamics of two tunnel-coupled chains after a quench in the tunneling strength is performed and the two systems are allowed to evolve independently. We describe the form
Universal dynamics of a soliton after an interaction quench
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

We report analytic results for the correlation functions of long-range quantum Ising models in arbitrary dimension. In particular, we focus on the long-time evolution and the relevant timescales on
Relaxation dynamics of two coherently coupled one-dimensional bosonic gases
Abstract In this work we consider the non-equilibrium dynamics of two tunnel coupled bosonic gases which are created from the coherent splitting of a one-dimensional gas. The consequences of the

Quench dynamics and nonequilibrium phase diagram of the bose-hubbard model.
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.
Prethermalization in quenched spinor condensates
Motivated by recent experiments, we consider the dynamics of spin-1 spinor condensates after a quantum quench from the polar to ferromagnetic state from varying the quadratic Zeeman field q. We apply

Thermalization after an interaction quench in the Hubbard model.
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
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∗.
Crossover from adiabatic to sudden interaction quenches in the Hubbard model: prethermalization and non-equilibrium dynamics
