Bose-Einstein condensation into non-equilibrium states studied by condensate focusing
I. Shvarchuck, Ch. Buggle, D. S. Petrov +7
We report the formation of Bose-Einstein condensates into non-equilibrium states. Our condensates are much longer than equilibrium condensates with the same number of atoms, show s…

Phase-fluctuating 3D condensates in elongated traps
D. S. Petrov, G. V. Shlyapnikov, J. T. M. Walraven
We find that in very elongated 3D trapped Bose gases, even at temperatures far below the BEC transition temperature Tc, the equilibrium state will be a 3D condensate with fluctuati…

Regimes of quantum degeneracy in trapped 1D gases
D. S. Petrov, G. V. Shlyapnikov, J. T. M. Walraven
We discuss the regimes of quantum degeneracy in a trapped 1D gas and obtain the diagram of states. Three regimes have been identified: the BEC regimes of a true condensate and quas…
