Observation of vortex dipoles in an oblate Bose-Einstein condensate
T. W. Neely, E. C. Samson, A. S. Bradley +2
We report experimental observations and numerical simulations of the formation, dynamics, and lifetimes of single and multiply charged quantized vortex dipoles in highly oblate dil…
Decay of a quantum vortex: test of non-equilibrium theories for warm Bose-Einstein condensates
S. J. Rooney, A. S. Bradley, P. B. Blakie
The decay of a vortex from a non-rotating high temperature Bose-Einstein condensate (BEC) is modeled using the stochastic projected Gross-Pitaevskii equation (SPGPE). In order to e…
Temporal coherence, anomalous moments, and pairing correlations in the classical-field description of a degenerate Bose gas
T. M. Wright, P. B. Blakie, R. J. Ballagh
The coherence properties of degenerate Bose gases have usually been expressed in terms of spatial correlation functions, neglecting the rich information encoded in their temporal b…
Vortex pairing in two-dimensional Bose gases
Christopher J. Foster, P. Blair Blakie, Matthew J. Davis
Recent experiments on ultracold Bose gases in two dimensions have provided evidence for the existence of the Berezinskii-Kosterlitz-Thouless (BKT) phase via analysis of the interfe…
Coding Guidelines for Prolog
Michael A. Covington, Roberto Bagnara, Richard A. O'Keefe +2
Coding standards and good practices are fundamental to a disciplined approach to software projects, whatever programming languages they employ. Prolog programming can benefit from…
Precession of Vortices in Dilute Bose-Einstein Condensates at Finite Temperature
B. G. Wild, D. A. W. Hutchinson
We demonstrate that the precessional frequencies of vortices in Bose Einstein condensates (BECs) are determined by a conservation law, and not by the lowest lying excitation energy…
Nonequilibrium dynamics of vortex arrest in a finite-temperature Bose-Einstein condensate
T. M. Wright, A. S. Bradley, R. J. Ballagh
We perform finite-temperature dynamical simulations of the arrest of a rotating Bose-Einstein condensate by a fixed trap anisotropy, using a Hamiltonian classical-field method. We…
Cooling and control of a cavity opto-electromechanical system
Kwan H. Lee, Terry G. McRae, Glen I. Harris +2
We implement a cavity opto-electromechanical system integrating electrical actuation capabilities of nanoelectromechanical devices with ultrasensitive mechanical transduction achie…
Quantitative test of mean-field description of a trapped two-dimensional Bose gas
R. N. Bisset, P. B. Blakie
We investigate the accuracy of two mean-field theories of the trapped two-dimensional Bose gas at predicting transition region properties by comparison to non-perturbative classica…
Finite-temperature dynamics of a single vortex in a Bose-Einstein condensate: Equilibrium precession and rotational symmetry breaking
T. M. Wright, A. S. Bradley, R. J. Ballagh
We consider a finite-temperature Bose-Einstein condensate in a quasi-two-dimensional trap containing a single precessing vortex. We find that such a configuration arises naturally…
Strong coupling cavity QED using rare-earth-ion dopants in monolithic resonators: what you can do with a weak oscillator
D. L. McAuslan, J. J. Longdell, M. J. Sellars
We investigate the possibility of achieving the strong coupling regime of cavity quantum electrodynamics using rare earth ions as impurities in monolithic optical resonators. We co…
Geometric scaling in the spectrum of an electron captured by a stationary finite dipole
Dániel Schumayer, Brandon P. van Zyl, Rajat K. Bhaduri +1
We examine the energy spectrum of a charged particle in the presence of a {\it non-rotating} finite electric dipole. For {\emph{any}} value of the dipole moment above a certain…
Quantum limited particle sensing in optical tweezers

M. K. Olsen, A. S. Bradley
Numerical stochastic integration is a powerful tool for the investigation of quantum dynamics in interacting many body systems. As with all numerical integration of differential eq…

A practical finite temperature theory is developed for the superfluid regime of a weakly interacting Bose gas in an optical lattice with additional harmonic confinement. We derive…
Non-classical photon streams using rephased amplified spontaneous emission
Patrick M. Ledingham, William R. Naylor, Jevon J. Longdell +2
We present a fully quantum mechanical treatment of optically rephased photon echoes. These echoes exhibit noise due to amplified spontaneous emission, however this noise can be see…
