Quantum kinetic theory VII: The influence of vapor dynamics on condensate growth
M. J. Davis, C. W. Gardiner, R. J. Ballagh
We extend earlier models of the growth of a Bose-Einstein condensate to include the full dynamical effects of the thermal cloud by numerically solving a modified quantum Boltzmann…
Meanfield treatment of Bragg scattering from a Bose-Einstein condensate
Peter B. Blakie, Robert J. Ballagh
A unified semiclassical treatment of Bragg scattering from Bose-Einstein condensates is presented. The formalism is based on the Gross-Pitaevskii equation driven by classical light…
RF coupling of a Bose-Einstein condensate in a TOP trap
J. L. Martin, C. R. McKenzie, N. R. Thomas +2
A radio frequency (RF) transition is used to convert a pure F=2,mF=2 87Rb Bose-Einstein condensate confined in a TOP trap to a mixture of F=2,mF=2 and F=2,mF=1 states. We show that…
Output coupling of a Bose-Einstein condensate formed in a TOP trap
J. L. Martin, C. R. McKenzie, N. R. Thomas +5
Two distinct mechanisms are investigated for transferring a pure 87Rb Bose-Einstein condensate in the F = 2, mF = 2 state into a mixture of condensates in all the mF states within…
Formation of Ramsey Fringes in Double Bose-Einstein Condensates
A. Eschmann, R. J. Ballagh, B. M. Caradoc-Davies
Numerical simulations of Ramsey fringe formation in double Bose condensates are carried out in two spatial dimensions. The effects of meanfield nonlinearity and diffusion in the co…
Dressed States of a two component Bose-Einstein Condensate
P. B. Blakie, R. J. Ballagh, C. W. Gardiner
A condensate with two internal states coupled by external electromagnetic radiation, is described by coupled Gross Pitaevskii equations, whose eigenstates are analogous to the dres…
