Bragg spectroscopy of an accelerating condensate with solitary-wave behaviour
K J Challis, R J Ballagh
We present a theoretical treatment of Bragg spectroscopy of an accelerating condensate in a solitary-wave state. Our treatment is based on the Gross-Pitaevskii equation with an opt…
Adiabatic cooling of Fermions in an optical lattice
P. B. Blakie, A. Bezett
The entropy-temperature curves are calculated for non-interacting fermions in a 3D optical lattice. These curves facilitate understanding of how adiabatic changes in the lattice de…
Solitary-wave description of condensate micro-motion in a time-averaged orbiting potential trap
K. J. Challis, R. J. Ballagh, C. W. Gardiner
We present a detailed theoretical analysis of micro-motion in a time-averaged orbiting potential trap. Our treatment is based on the Gross-Pitaevskii equation, with the full time d…
O(1) Reversible Tree Navigation Without Cycles
Richard A. O'Keefe
Imperative programmers often use cyclically linked trees in order to achieve O(1) navigation time to neighbours. Some logic programmers believe that cyclic terms are necessary to a…
Imaging of s and d partial-wave interference in quantum scattering of identical bosonic atoms
Nicholas R. Thomas, Niels Kjaergaard, Paul S. Julienne +1
We report on the direct imaging of s and d partial-wave interference in cold collisions of atoms. Two ultracold clouds of Rb87 atoms were accelerated by magnetic fields to collide…
