We consider the non-equilibrium dynamics of a weakly interacting Bose gas tightly confined to a highly elongated double well potential. We use a self-consistent time-dependent Hartree--Fock approximation in combination with a projection of the full three-dimensional theory to several coupled one-dimensional channels. This allows us to model the time-dependent splitting and phase imprinting of a gas initially confined to a single quasi one-dimensional potential well and obtain a microscopic… Expand
Quantum quenches in an interacting field theory: full quantum evolution vs. semi-classical approximations
We develop a truncated Hamiltonian method to investigate the dynamics of the $(1+1)d~\phi^4$ theory following quantum quenches. The results are compared to two different semi-classical approaches,Expand

Hydrodynamics of weak integrability breaking
We review recent progress in understanding nearly integrable models within the framework of generalized hydrodynamics (GHD). Integrable systems have infinitely many conserved quantities and stableExpand
Inhomogeneous quantum quenches in the sine-Gordon theory
We study inhomogeneous quantum quenches in the attractive regime of the sine–Gordon model. In our protocol, the system is prepared in an inhomogeneous initial state in finite volume by coupling theExpand
Quenches in initially coupled Tomonaga-Luttinger Liquids: a conformal field theory approach
We study the quantum quench in two coupled Tomonaga-Luttinger Liquids (TLLs), from the off-critical to the critical regime, relying on the conformal field theory approach and the known solutions forExpand


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 theExpand
Relaxation to a Phase-Locked Equilibrium State in a One-Dimensional Bosonic Josephson Junction.
An empirical model based on the analogy with the anharmonic oscillator is proposed to describe the effect of various experimental parameters on the nonequilibrium tunnel dynamics of two coupled one-dimensional Bose-Einstein quasicondensates deep in the Josephson regime. Expand
Nonequilibrium dynamics of coupled Luttinger liquids
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 formExpand
Experimental evidence for the breakdown of a Hartree-Fock approach in a weakly interacting Bose gas.
Numerical calculations based on Bogoliubov theory give an estimate of the crossover density in agreement with experimental results, and it is shown that a Hartree-Fock approach fails to predict the existence of the quasicondensate in the center of the cloud. Expand
Linear response theory for a pair of coupled one-dimensional condensates of interacting atoms
We use the quantum sine-Gordon model to describe the low-energy dynamics of a pair of coupled one-dimensional condensates of interacting atoms. We show that the nontrivial excitation spectrum of theExpand
Josephson tunnelling of a phase-imprinted Bose?Einstein condensate in a time-dependent double-well potential
This paper discusses the feasibility of experimental control of the flow direction of atomic Bose–Einstein condensates in a double-well potential using phase imprinting. The flow is induced by theExpand

Correlations and dynamics of tunnel-coupled one-dimensional Bose gases
We present a series of experiments performed with two ultracold one-dimensional Bose gases (rubidium atoms) in a double well potential. Employing matter-wave interference, we can measure theExpand
Non-equilibrium coherence dynamics in one-dimensional Bose gases.

Hybrid Semiclassical Theory of Quantum Quenches in One-Dimensional Systems.
A hybrid semiclassical method to study the time evolution of one-dimensional quantum systems in and out of equilibrium by a modified time-evolving block decimation method while treating orbital quasiparticle motion classically is developed. Expand
