Hartree-Fock Theory for Double Condensates
نویسندگان
چکیده
We present the first theoretical treatment that accounts in detail for a recent observation of overlapping Bose-Einstein condensates of two different 87Rb hyperfine states [C. J. Myatt et al., Phys. Rev. Lett. 78, 586 (1997)]. Despite the complicated geometry, we have completed a threedimensional Hartree-Fock calculation for the coupled condensates. The calculation explains a number of its key properties: (i) The manner in which one condensate partially wraps around the other, (ii) the mean separation between the two condensates including the effects of gravity and of their mutual interaction, and (iii) the surprisingly long lifetime of the trap.

Dipolar Bose-Einstein condensates at finite temperature
We study a Bose-Einstein condensate of a dilute gas with dipolar interactions, at finite temperature, using the Hartree-Fock-Bogoliubov theory within the Popov approximation. An additional approximation involving the dipolar exchange interaction is made to facilitate the computation. We calculate the temperature dependence of the condensate fraction of a condensate confined in a cylindrically s...

متن کاملQuantized circulation in dilute Bose–Einstein condensates
We compute using a microscopic mean-field theory the structure and the quasiparticle excitation spectrum of a dilute, trapped Bose–Einstein condensate penetrated by an axisymmetric vortex line. The Gross–Pitaevskii equation for the condensate and the coupled Hartree–Fock–Bogoliubov–Popov equations describing the elementary excitations are solved self-consistently using finite-difference methods...
متن کاملEffect of the thermal gas component on the stability of vortices in trapped Bose–Einstein condensates
We study the stability of vortices in trapped single-component Bose–Einstein condensates within self-consistent mean-field theories; in particular, we consider the Hartree–Fock–Bogoliubov–Popov theory and its recently proposed gapless extensions. It is shown that for sufficiently repulsively interacting systems the anomalous negative-energy modes related to vortex instabilities are lifted to po...
