Analytic solutions for the spatial character and coherence properties of light scattered from two dipole-coupled atoms
Petra Fersterer, R. J. Ballagh
Analytic solutions for steady-state expectation values of atomic quantities and second order correlations are obtained for a fully quantum treatment of two stationary dipole-couple…
C-Field Methods for Non-Equilibrium Bose Gases
Matthew J. Davis, Tod M. Wright, P. Blair Blakie +3
We review c-field methods for simulating the non-equilibrium dynamics of degenerate Bose gases beyond the mean-field Gross-Pitaevskii approximation. We describe three separate appr…
Probing the quantum state of a 1D Bose gas using off-resonant light scattering
A. G. Sykes, R. J. Ballagh
We present a theoretical treatment of coherent light scattering from an interacting 1D Bose gas at finite temperatures. We show how this can provide a nondestructive measurement of…
Effective Field Theory for Atom-Molecule Systems III: Dynamic Effects of a Feshbach Resonance on Bragg scattering from a Bose-Einstein Condensate
Catarina E. Sahlberg, R. J. Ballagh, C. W. Gardiner
We present a theoretical model for Bragg scattering from a Bose-Einstein condensate (BEC) in the vicinity of a magnetic Feshbach resonance, using a two c-field formalism, one c-fie…
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…
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…
