Collisions of solitary waves in condensates beyond mean-field theory

A Sreedharan, S Choudhury, R Mukherjee, A Streltsov… - Physical Review A, 2020 - APS
Bright solitary waves in a Bose-Einstein condensate contain thousands of identical atoms
held together despite their only weakly attractive contact interactions. They nonetheless …

Localization landscape for interacting Bose gases in one-dimensional speckle potentials

F Stellin, M Filoche, F Dias - Physical Review A, 2023 - APS
While the properties and the shape of the ground state of a gas of ultracold bosons are well
understood in harmonic potentials, they remain for a large part unknown in the case of …

Hyper-entangling mesoscopic bound states

We predict hyper-entanglement generation by binary scattering of mesoscopic bound states,
considering solitary waves in Bose–Einstein condensates containing thousands of identical …

Observation of the algebraic localization-delocalization transition in a one-dimensional disordered potential with a bias force

G Berthet, L Lavoine, MK Parit, A Brolis, A Boissé… - Physical Review …, 2020 - APS
One-dimensional (1D) Anderson localization phenomena are strongly affected by a bias
force or equivalently a voltage in electronic systems. We experimentally study this case …
