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…
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…
Phase transition on the Toeplitz algebra of the affine semigroup over the natural numbers
Marcelo Laca, Iain Raeburn
We show that the group of orientation-preserving affine transformations of the rational numbers is quasi-lattice ordered by its subsemigroup ${\…
Finite temperature theory of superfluid bosons in optical lattices
D. Baillie, P. B. Blakie
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…
Transition region properties of a trapped quasi-two-dimensional degenerate Bose gas
R. N. Bisset, P. B. Blakie
The c-field simulation technique is used to study a trapped quasi-two dimensional Bose gas. We calculate the central curvature of the system density and fluctuations of the condens…
Critical temperature of a Bose gas in an optical lattice
D. Baillie, P. B. Blakie
We present theory for the critical temperature of a Bose gas in a combined harmonic lattice potential based on a mean-field description of the system. We develop practical expressi…
