Abstract A system of identical bosons with short-range (contact) interactions is studied. Their motion is confined to one dimension by a tight lateral trapping potential and, additionally, subject to a weak harmonic confinement in the longitudinal direction. Finite delay time associated with penetration of quantum particles through each other in the course of a pairwise one-dimensional collision in the presence of the longitudinal potential makes the system non-integrable and, hence, provides a… 
Thermalization of a Trapped One-Dimensional Bose Gas via Diffusion.
It is shown that whenever the underlying integrability of the gas is broken by the presence of the external potential, the inevitable diffusive rearrangements between the quasiparticles, quantified by the diffusion constants of theGas, eventually lead the system to thermalize at late times.
Relaxation of bosons in one dimension and the onset of dimensional crossover
We study ultra-cold bosons out of equilibrium in a one-dimensional (1D) setting and probe the breaking of integrability and the resulting relaxation at the onset of the crossover from one to three
Collective oscillations of a trapped atomic gas in low dimensions and thermodynamics of one-dimensional Bose gas
Ultracold atoms are exceptional tools to explore the physics of quantum matter. In fact, the high degree of tunability of ultracold Bose and Fermi gases makes them ideal systems for quantum
Controlling integrability in a quasi-one-dimensional atom-dimer mixture
We analytically study the atom-dimer scattering problem in the near-integrable limit when the oscillator length l0 of the transverse confinement is smaller than the dimer size, ∼l02/|a|, where a<0 is
Enhanced oscillation lifetime of a Bose–Einstein condensate in the 3D/1D crossover
We have measured the damped motion of a trapped Bose–Einstein condensate, oscillating with respect to a thermal cloud. The cigar-shaped trapping potential provides enough transverse confinement that
Thermalization near Integrability in a Dipolar Quantum Newton's Cradle
Isolated quantum many-body systems with integrable dynamics generically do not thermalize when taken far from equilibrium. As one perturbs such systems away from the integrable point, thermalization
One-dimensional atomic superfluids as a model system for quantum thermodynamics
In this chapter we will present the one-dimensional (1d) quantum degenerate Bose gas (1d superfluid) as a testbed to experimentally illustrate some of the key aspects of quantum thermodynamics.
Hydrodynamic versus collisionless dynamics of a one-dimensional harmonically trapped Bose gas
By using a sum rule approach we investigate the transition between the hydrodynamic and the collisionless regime of the collective modes in a 1D harmonically trapped Bose gas. Both the weakly
Breathing mode in the Bose-Hubbard chain with a harmonic trapping potential
We investigate the breathing mode of harmonically trapped bosons in an optical lattice at small site occupancies. The Bose-Hubbard model with a trapping potential is used to describe the
Topological pumping of a 1D dipolar gas into strongly correlated prethermal states
Cycling the contact interaction between dipolar dysprosium atoms creates a series of excited nonthermal quantum states that are an energy-space topological pump (caused by a quantum holonomy) and offers an unexplored topological pumping method to create a hierarchy of increasingly excited prethermal states.


Weakly interacting Bose gas in the one-dimensional limit.
A new interferometric method is introduced to distinguish the quasicondensate fraction of the gas from the thermal cloud at finite temperature and at the lowest temperatures the transverse-momentum distribution exhibits a residual dependence on the line density n(1D), characteristic for 1D systems.
Thermalization in a quasi-one-dimensional ultracold bosonic gas
We study the collisional processes that can lead to thermalization in one-dimensional (1D) systems. For two-body collisions, excitations of transverse modes are the prerequisite for energy exchange
Fermionization dynamics of a strongly interacting one-dimensional Bose gas after an interaction quench
We study the dynamics of a one-dimensional Bose gas after a sudden change of the interaction strength from zero to a finite value using the numerical time-evolving block decimation (TEBD) algorithm.
Restoring integrability in one-dimensional quantum gases by two-particle correlations
We show that thermalization and the breakdown of integrability in the one dimensional Lieb-Liniger model caused by local three-body elastic interactions is suppressed by pairwise quantum correlations
Breakdown of integrability in a quasi-1D ultracold bosonic gas.
We demonstrate that virtual excitations of higher radial modes in an atomic Bose gas in a tightly confining waveguide result in effective three-body collisions that violate integrability in this
A gas of one-dimensional Bose particles interacting via a repulsive delta-function potential has been solved exactly. All the eigenfunctions can be found explicitly and the energies are given by the
Atomic Scattering in the Presence of an External Confinement and a Gas of Impenetrable Bosons
We calculate, within the pseudopotential approximation, a one-dimensional scattering amplitude and effective one-dimensional interaction potential for atoms confined transversally by an atom
Exact Analysis of an Interacting Bose Gas. II. The Excitation Spectrum
We continue the analysis of the one-dimensional gas of Bose particles interacting via a repulsive delta function potential by considering the excitation spectrum. Among other things we show that: (i)
Collective oscillations of a classical gas confined in harmonic traps
Starting from the Boltzmann equation, we calculate the frequency and the damping of the collective oscillations of a classical gas confined by a harmonic potential. Both the monopole and quadrupole
