Splitting bright matter-wave solitons on narrow potential barriers: Quantum to classical transition and applications to interferometry
We study bright solitons in the Gross-Pitaevskii equation as they are split and recombined in
a low-energy system. We present analytic results determining the general region in which a …

Scattering bright solitons: Quantum versus mean-field behavior
We investigate scattering bright solitons off a potential using both analytical and numerical
methods. Our paper focuses on low kinetic energies for which differences between the mean …

Bright-soliton quantum superpositions: signatures of high-and low-fidelity states
B Gertjerenken - Physical Review A—Atomic, Molecular, and Optical …, 2013 - APS
Scattering quantum bright solitons off barriers has been predicted to lead to nonlocal
quantum superpositions, in particular the NOON state. The focus of this paper lies on …

From short-time diffusive to long-time ballistic dynamics: The unusual center-of-mass motion of quantum bright solitons
C Weiss, SA Gardiner, HP Breuer - Physical Review A, 2015 - APS
Brownian motion is ballistic on short time scales and diffusive on long time scales. Our
theoretical investigations indicate that one can observe the exact opposite—an “anomalous …

Entangling two distinguishable quantum bright solitons via collisions
The generation of mesoscopic Bell states via collisions of distinguishable bright solitons has
been suggested in Phys. Rev. Lett. 111, 100406 (2013). Here, we extend our former …

Phase-matching condition for enhanced entanglement of colliding indistinguishable quantum bright solitons in a harmonic trap
We investigate finite number effects in collisions between two states of an initially well
defined number of identical bosons with attractive contact interactions, oscillating in the …

Finite-temperature phase transition in a homogeneous one-dimensional gas of attractive bosons
C Weiss - arXiv preprint arXiv:1610.09070, 2016 - arxiv.org
In typical one-dimensional models the Mermin-Wagner theorem forbids long range order,
thus preventing finite-temperature phase transitions. We find a finite-temperature phase …
