Numerical method for evolving the Projected Gross-Pitaevskii equation
P. B. Blakie
In this paper we describe a method for evolving the projected Gross-Pitaevskii equation (PGPE) for a Bose gas in a harmonic oscillator potential. The central difficulty in solving…
Theory of correlations between ultra-cold bosons released from an optical lattice
E. Toth, A. M. Rey, P. B. Blakie
In this paper we develop a theoretical description of the correlations between ultra-cold bosons after free expansion from confinement in an optical lattice. We consider the system…
Bose-Einstein Condensation from a Rotating Thermal Cloud: Vortex Nucleation and Lattice Formation
A. S. Bradley, C. W. Gardiner, M. J. Davis
We develop a stochastic Gross-Pitaveskii theory suitable for the study of Bose-Einstein condensation in a {\em rotating} dilute Bose gas. The theory is used to model the dynamical…
Superfluidity of an interacting trapped quasi-2D Bose gas
T. P. Simula, M. J. Davis, P. B. Blakie
We investigate the harmonically trapped interacting Bose gas in a quasi-2D geometry using the classical field method. The system exhibits quasi-long-range order and non-classical r…
Two point correlations of a trapped interacting Bose gas at finite temperature
A. Bezett, E. Toth, P. B. Blakie
We develop a computationally tractable method for calculating correlation functions of the finite temperature trapped Bose gas that includes the effects of s-wave interactions. Our…
