Singularity formation in the Gross-Pitaevskii Equation and Collapse in BEC
A. V. Rybin, I. P. Vadeiko, G. G. Varzugin +1
We study a mechanism of collapse of the condensate wave function in the Gross-Pitaevskii theory with attractive interparticle interaction. We reformulate the Gross-Pitaevskii equat…

Coherent quantum oscillations in coupled traps with ultracold atoms
N. M. Bogoliubov, J. Timonen, M. B. Zvonarev
The dynamics of two traps with ultracold atoms and connected by Josephson type coupling, is shown to exhibit a transition from dispersive dynamics to localized coherent oscillation…
