We develop the number-conserving approach, which has previously been used in a single-component Bose-Einstein condensed dilute atomic gas, to describe consistent coupled condensate and noncondensate number dynamics, to an n -component condensate. The... Read More about Number-conserving approaches to n-component Bose-Einstein condensates.

Splitting bright matter-wave solitons on narrow potential barriers: Quantum to classical transition and applications to interferometry (2014)
Journal Article
Helm, J., Rooney, S., Weiss, C., & Gardiner, S. (2014). Splitting bright matter-wave solitons on narrow potential barriers: Quantum to classical transition and applications to interferometry. Physical Review A, 89(3), Article 033610. https://doi.org/10.1103/physreva.89.033610

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 soliton may not be split on a potential barrier and confirm these...

Phase-matching condition for enhanced entanglement of colliding indistinguishable quantum bright solitons in a harmonic trap (2014)
Journal Article

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 presence of harmonic confinement in one dimension. We investigate t... Read More about Phase-matching condition for enhanced entanglement of colliding indistinguishable quantum bright solitons in a harmonic trap.
