Collisional matter-phase damping in Bose-condensed gas
L. I. Plimak, M. J. Collett, D. F. Walls
Collisional damping of the excitations in a Bose-condensed gas is investigated over the wide range of energies and temperatures. Numerical results for the damping rate are presente…
Spontaneous photon emission stimulated by two Bose condensates
C. M. Savage, Janne Ruostekoski, Dan F. Walls
We show that the phase difference of two overlapping ground state Bose-Einstein condensates can effect the optical spontaneous emission rate of excited atoms. Depending on the phas…
Collapses and Revivals of Collective Excitations in Trapped Bose Condensates
R. Graham, D. F. Walls, M. J. Collett +2
We present a quantum theory of low-lying excitations in a trapped Bose condensate with finite particle numbers. We find that even at zero temperature condensate number fluctuations…
Interference of Resonance Fluorescence from two four-level atoms
T. Wong, S. M. Tan, M. J. Collett +1
In a recent experiment by Eichmann et al., polarization-sensitive measurements of the fluorescence from two four-level ions driven by a linearly polarized laser were made. Dependin…
Collapses and revivals in the interference between two Bose-Einstein condensates formed in small atomic samples
E. M. Wright, T. Wong, M. J. Collett +2
We investigate the quantum interference between two Bose-Einstein condensates formed in small atomic samples composed of a few thousand atoms both by imposing Bose broken gauge sym…
Phase dependent spectrum of scattered light from two Bose condensates
Janne Ruostekoski, Dan F. Walls
We calculate the spectrum of the scattered light from quantum degenerate atomic gases obeying Bose-Einstein statistics. The atoms are assumed to occupy two ground states which are…
