  journal={arXiv: Quantum Gases},
When an interaction quench by a factor of four is applied to an attractive Bose-Einstein condensate, a higher-order quantum bright soliton exhibiting robust oscillations is predicted in the semiclassical limit by the Gross-Pitaevskii equation. Combining matrix-product state simulations of the Bose-Hubbard Hamiltonian with analytical treatment via the Lieb-Liniger model and the eigenstate thermalization hypothesis, we show these oscillations are absent. Instead, one obtains a large stationary…

Dissociation of One-Dimensional Matter-Wave Breathers due to Quantum Many-Body Effects.
The ab initio Bethe ansatz dynamics is used to predict the dissociation of one-dimensional cold-atom breathers that are created by a quench from a fundamental soliton and is found to be a robust quantum many-body effect in the mean-field (MF) limit.
Dynamics of nonlinear Schrödinger breathers in a potential trap.
We consider the evolution of the 2-soliton (breather) of the nonlinear Schrödinger equation on a semi-infinite line with the zero boundary condition and a linear potential, which corresponds to the
Creation and Characterization of Matter-Wave Breathers.
We report the creation of quasi-1D excited matter-wave solitons, "breathers," by quenching the strength of the interactions in a Bose-Einstein condensate with attractive interactions. We characterize

Dark solitons in Bose-Einstein condensates
Summary form only given. One of the most striking aspects of Bose-Einstein condensates (BEC) of weakly interacting gases are the nonlinear properties of these systems. Of particular interest are
Quantum entangled dark solitons formed by ultracold atoms in optical lattices.
It is found that quantum effects cause the soliton to fill in, and soliton-soliton collisions become inelastic, in strong contrast to the predictions of mean-field theory.
Spontaneous soliton formation and modulational instability in Bose-Einstein condensates.
The dynamics of an elongated attractive Bose-Einstein condensate in an axisymmetric harmonic trap is studied. It is shown that density fringes caused by self-interference of the condensate order
Beyond-mean-field behavior of large Bose-Einstein condensates in double-well potentials
For the dynamics of Bose-Einstein condensates (BECs), differences between mean-field (Gross-Pitaevskii) physics and N-particle quantum physics often disappear if the BEC becomes larger and larger. In
Temperatures are not useful to characterise bright-soliton experiments for ultra-cold atoms
Contrary to many other translationally invariant one-dimensional models, the low-temperature phase for an attractively interacting one-dimensional Bose-gas (a quantum bright soliton) is stable
Correspondence between dark solitons and the type II excitations of the Lieb-Liniger model
A one-dimensional model of bosons with repulsive short-range interactions, solved analytically by Lieb and Liniger many years ago, predicts existence of two branches of elementary excitations. One of
Nonlocal quantum superpositions of bright matter-wave solitons and dimers
The scattering of bright quantum solitons at barrier potentials in one-dimensional geometries is investigated. Such protocols have been predicted to lead to the creation of nonlocal quantum
Internal structure of a quantum soliton and classical excitations due to trap opening
We analytically solve two problems that may be useful in the context of the recent observation of matter wave bright solitons in a one-dimensional attractive atomic Bose gas. The first problem is
Dynamics of the Bose-Einstein condensate: quasi-one-dimension and beyond
It is shown that the quasi-one-dimensional Bose-Einstein condensate is experimentally accessible and rich in intriguing phenomena. We demonstrate numerically and analytically the existence, stability
Formation of bright matter-wave solitons during the collapse of attractive Bose-Einstein condensates.
Bright matter-wave solitons form during the collapse of (85)Rb condensates in a three-dimensional (3D) magnetic trap using a Feshbach resonance to suddenly switch the atomic interactions from repulsive to attractive.
