Hydrodynamic modes of a 1D trapped Bose gas
J. N. Fuchs, X. Leyronas, R. Combescot
We consider two regimes where a trapped Bose gas behaves as a one-dimensional system. In the first one the Bose gas is microscopically described by 3D mean field theory, but the tr…

Castaing's instability in a trapped ultra-cold gas
J. N. Fuchs, O. Prevote, D. M. Gangardt
We consider a trapped ultra-cold gas of (non-condensed) bosons with two internal states (described by a pseudo spin) and study the stability of a longitudinal pseudo spin polarizat…
