Stability of spherically trapped three-dimensional Bose-Einstein condensates against macroscopic fragmentation
Philipp Bader, Uwe R. Fischer
We consider spherically trapped Bose gases in three dimensions with contact interactions, and investigate whether the Bose-Einstein condensate at zero temperature is stable against…

Interacting trapped bosons yield fragmented condensate states in low dimensions
Uwe R. Fischer, Philipp Bader
We investigate the level population statistics and degree of coherence encoded in the single-particle density matrix of harmonically trapped low-dimensional [quasi-one-dimensional…
