A number-conserving approach to a minimal self-consistent treatment of condensate and non-condensate dynamics in a degenerate Bose gas
S. A. Gardiner, S. A. Morgan
We describe a number conserving approach to the dynamics of Bose-Einstein condensed dliute atomic gases. This builds upon the works of Gardiner [C. W. Gardiner, Phys. Rev. A 56, 14…
Quantitative test of thermal field theory for Bose-Einstein condensates II
S. A. Morgan
We have recently derived a gapless theory of the linear response of a Bose-condensed gas to external perturbations at finite temperature and used it to explain quantitatively the m…
Novel Dynamical Resonances in Finite-Temperature Bose-Einstein Condensates
A. J. Geddes, S. A. Morgan, D. A. W. Hutchinson
We describe a variety of intriguing mode-coupling effects which can occur in a confined Bose-Einstein condensed system at finite temperature. These arise from strong interactions b…
Finite temperature theory of the trapped two dimensional Bose gas
Christopher Gies, Brandon van Zyl, S. A. Morgan +1
We present a Hartree-Fock-Bogoliubov (HFB) theoretical treatment of the two-dimensional trapped Bose gas and indicate how semiclassical approximations to this and other formalisms…
The response of Bose-Einstein condensates to external perturbations at finite temperature
S. A. Morgan
We present a theory of the linear response of a Bose-condensed gas to external perturbations at finite temperature. The theory developed here is the basis of a recent quantitative…
Microcanonical temperature for a classical field: application to Bose-Einstein condensation
M. J. Davis, S. A. Morgan
We show that the projected Gross-Pitaevskii equation (PGPE) can be mapped exactly onto Hamilton's equations of motion for classical position and momentum variables. Making use of t…
