Strongly Interacting Fermi Gases of Atoms Confined in a Harmonic Trap
Yeong E. Kim, Alexander L. Zubarev
Dynamics of strongly interacting Fermi gases, consisting of a 50-50 mixture of two different fermionic species, is investigated. For the equation of state we consider a Padé [2/2]…

Cold Bose Gases near Feshbach Resonances
Yeong E. Kim, Alexander L. Zubarev
The lowest order constrained variational method [Phys. Rev. Lett. 88, 210403 (2002)] has been generalized for a dilute (in the sense that the range of interatomic potential is smal…

Beyond the Thomas-Fermi Approximation for Nonlinear Dynamics of Trapped Bose-Condensed Gases
Alexander L. Zubarev, Yeong E. Kim
We present an analytical approximation for nonlinear dynamics of trapped Bose-co ndensed gases. The new approximation is a substantial improvement over the Thomas-Fermi approximati…
