in trapped Bose gases
نویسنده
چکیده
We study the dynamics of condensate formation in an inhomogeneous trapped Bose gas with a positive interatomic scattering length. We take into account both the nonequilibrium kinetics of the thermal cloud and the Hartree-Fock mean-field effects in the condensed and the noncondensed parts of the gas. We solve our equations numerically by assuming that the thermal component behaves ergodically and that the condensate grows adiabatically. The condensate is also treated within the Thomas-Fermi approximation. We find excellent agreement between theory and experiment, for a broad range of equilibrium condensate numbers. ∗Permanent address: Department of Physics, Queen’s University, Kingston, Ontario, Canada K7L 3N6.

Two-Fluid Hydrodynamics in Trapped Bose Gases and in Superfluid Helium
A review is given of recent theoretical work on the superfluid dynamics of trapped Bose gases at finite temperatures, where there is a significant fraction of non-condensate atoms. One can now reach large enough densities and collision cross-sections needed to probe the collective modes in the collisiondominated hydrodynamic region where the gas exhibits characteristic superfluid behavior invol...
متن کاملParticle fluctuations in nonuniform and trapped Bose gases
The problem of particle fluctuations in arbitrary nonuniform systems with BoseEinstein condensate is considered. This includes the case of trapped Bose atoms. It is shown that the correct description of particle fluctuations for any nonuniform system of interacting atoms always results in thermodynamically normal fluctuations.
متن کاملAtom lasers and phase coherence of atomic Bose gases
Using continuous radio-frequency waves a coherent beam of atoms can be extracted from a magnetically trapped gaseous Bose-Einstein condensate. These novel atomic beams have matter-wave properties that are very similar to those of laser light in classical optics and are therefore called atom lasers. Furthermore, coupling out atoms from a Bose gas allows one to probe the dramatic changes in the p...
متن کاملCold quantum gases: coherent quantum phenomena from Bose-Einstein condensation to BCS pairing of fermions
Studies of trapped quantum gases of bosons and of fermions have opened up a new range of manybody problems, having a strong overlap with nuclear and neutron star physics. Topics discussed here include: the Bose yrast problem – how many-particle Bose systems carry extreme amounts of angular momentum; the infrared divergent structure of the transition to Bose condensation in a weakly interacting ...
متن کامل1 T c for trapped dilute Bose gases : a second - order result
For some time, the theoretical result for the transition temperature of a dilute three-dimensional Bose gas in an arbitrarily wide harmonic trap has been known to first order in the interaction strength. We extend that result to second order. The first-order result for a gas trapped in a harmonic potential can be computed in mean field theory (in contrast to the first order result for a uniform...
متن کاملPrincipal problems in Bose-Einstein condensation of dilute gases
A survey is given of the present state of the art in studying Bose-Einstein condensation of dilute atomic gases. The bulk of attention is focused on the principal theoretical problems, though the related experiments are also mentioned. Both uniform and nonuniform trapped gases are considered. Existing theoretical contradictions are critically analysed. A correct understanding of the principal t...
