Production Efficiency of Ultracold Feshbach Molecules in Bosonic and Fermionic Systems
E. Hodby, S. T. Thompson, C. A. Regal +5
We investigate the production efficiency of ultracold molecules in bosonic Rb and fermionic K when the magnetic field is swept across a Feshbach resonance. For adiaba…
Transition from Bose-Einstein Condensate to Berezinskii-Kosterlitz-Thouless Phase
T. P. Simula, M. D. Lee, D. A. W. Hutchinson
We obtain a phase diagram for a trapped two-dimensional ultra-cold Bose gas. We find a critical temperature above which the free energy of a state with a pair of vortices of opposi…
Properties of the stochastic Gross-Pitaevskii equation: Projected Ehrenfest relations and the optimal plane wave basis
A. S. Bradley, P. B. Blakie, C. W. Gardiner
We investigate the properties of the stochastic Gross-Pitaevskii equation describing a condensate interacting with a stationary thermal cloud derived by Gardiner and coworkers. We…
The Projected Gross-Pitaevskii Equation for harmonically confined Bose gases
P. Blair Blakie, Matthew J. Davis
We extend the Projected Gross Pitaevskii equation formalism of Davis et al. [Phys. Rev. Lett. \bf{87}, 160402 (2001)] to the experimentally relevant case of harmonic potentials. We…
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…
Many-body T-matrix of a two-dimensional Bose-Einstein condensate within the Hartree-Fock-Bogoliubov formalism
Christopher Gies, M. D. Lee, D. A. W. Hutchinson
In a two-dimensional Bose-Einstein condensate the reduction in dimensionality fundamentally influences collisions between the atoms. In the crossover regime from three to two dimen…
Quantum and classical fidelities for Gaussian states
H. Jeong, T. C. Ralph, W. P. Bowen
We examine the physical significance of fidelity as a measure of similarity for Gaussian states, by drawing a comparison with its classical counterpart. We find that the relationsh…
Observations on Sound Propagation in Rapidly Rotating Bose-Einstein Condensates
T. P. Simula, P. Engels, I. Coddington +3
Repulsive laser potential pulses applied to vortex lattices of rapidly rotating Bose-Einstein condensates create propagating density waves which we have observed experimentally and…
Nonlinear atom-optical delta-kicked harmonic oscillator using a Bose-Einstein condensate
G. J. Duffy, A. S. Mellish, K. J. Challis +1
We experimentally investigate the atom-optical delta-kicked harmonic oscillator for the case of nonlinearity due to collisional interactions present in a Bose-Einstein condensate.…
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…
Coherence properties of the two-dimensional Bose-Einstein condensate
Christopher Gies, D. A. W. Hutchinson
We present a detailed finite-temperature Hartree-Fock-Bogoliubov (HFB) treatment of the two-dimensional trapped Bose gas. We highlight the numerical methods required to obtain solu…
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…
Bragg Spectroscopy of ultracold atoms loaded in an optical lattice
Ana Maria Rey, P. Blair Blakie, Guido Pupillo +2
We study Bragg spectroscopy of ultra-cold atoms in one-dimensional optical lattices as a method for probing the excitation spectrum in the Mott insulator phase, in particular the o…
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…
Wannier states and Bose-Hubbard parameters for 2D optical lattices
P. B. Blakie, C. W. Clark
We consider the physical implementation of a 2D optical lattice with schemes involving 3 and 4 light fields. We illustrate the wide range of geometries available to the 3 beam latt…
Quantum turbulence in condensate collisions: an application of the classical field method
A. A. Norrie, R. J. Ballagh, C. W. Gardiner
We apply the classical field method to simulate the production of correlated atoms during the collision of two Bose-Einstein condensates. Our non-perturbative method includes the e…
Experimental investigation of early-time diffusion in the quantum kicked rotor using a Bose-Einstein condensate
G. Duffy, S. Parkins, T. Muller +3
We report the experimental observation of resonances in the early-time momentum diffusion rates for the atom-optical delta-kicked rotor. In this work a Bose-Einstein condensate pro…
