The steady state quantum statistics of a non-Markovian atom laser
J. J. Hope, G. M. Moy, M. J. Collett +1
We present a fully quantum mechanical treatment of a single-mode atomic cavity with a pumping mechanism and an output coupling to a continuum of external modes. This system is a sc…
Quantum state of two trapped Bose-Einstein condensates with a Josephson coupling
M. J. Steel, M. J. Collett
We consider the precise quantum state of two trapped, coupled Bose Einstein condensates in the two-mode approximation. We seek a representation of the state in terms of a Wigner-li…
Macroscopic superpositions of Bose-Einstein condensates
Janne Ruostekoski, M. J. Collett, Robert Graham +1
We consider two dilute gas Bose-Einstein condensates with opposite velocities from which a monochromatic light field detuned far from the resonance of the optical transition is coh…
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…
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…
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…
