A canonical approach to quantum fluctuations
Joanna Ruhl, Vanja Dunjko, Maxim Olshanii
We present a canonical formalism for computing quantum fluctuations of certain discrete degrees of freedom in systems governed by integrable partial differential equations with kno…
Massive particle interferometry with lattice solitons
Piero Naldesi, Juan Polo, Peter D. Drummond +4
We discuss an interferometric scheme employing interference of bright solitons formed as specific bound states of attracting bosons on a lattice. We revisit the proposal of Castin…
Massive particle interferometry with lattice solitons: robustness against ionization
Piero Naldesi, Peter D. Drummond, Vanja Dunjko +2
We revisit the proposal of Castin and Weiss [Phys. Rev. Lett. vol. 102, 010403 (2009)] for using the scattering of a quantum matter-wave soliton on a barrier in order to create a c…
The origin of the period- quasi-breathing in disk-shaped Gross-Pitaevskii breathers
J. Torrents, V. Dunjko, M. Gonchenko +2
We address the origins of the quasi-periodic breathing observed in [Phys. Rev.\ X vol. 9, 021035 (2019)] in disk-shaped harmonically trapped two-dimensional Bose condensates, where…
Triangular Gross-Pitaevskii breathers and Damski-Chandrasekhar shock waves
M. Olshanii, D. Deshommes, J. Torrents +3
The recently proposed map [arXiv:2011.01415] between the hydrodynamic equations governing the two-dimensional triangular cold-bosonic breathers [Phys. Rev. X 9, 021035 (2019)] and…
Creation and Characterization of Matter-Wave Breathers
De Luo, Yi Jin, Jason H. V. Nguyen +6
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 interactio…
