"Dissociation of One-Dimensional Matter-Wave Breathers due to Quantum Many-Body Effects." <i>Physical Review Letters,</i> 119, no. 22 (2017) American Physical Society: https://doi.org/10.1103/PhysRevLett.119.220401.https://hdl.handle.net/1911/98887We use the ab initio Bethe ansatz dynamics to predict the dissociation of one-dimensional cold-atom breathers that are created by a quench from a fundamental soliton. We find that the dissociation is a robust quantum many-body effect, while in the mean-field (MF) limit the dissociation is forbidden by the integrability of the underlying nonlinear Schrödinger equation. The analysis demonstrates the possibility to observe quantum many-body effects without leaving the MF range of experimental parameters. We find that the dissociation time is of the order of a few seconds for a typical atomic-soliton setting.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
