The study of the non-equilibrium dynamics in Bose-Einstein condensed gases has been dominated by the zero-temperature, mean field Gross-Pitaevskii formalism. Motivated by recent experiments on the reflection of condensates from silicon surfaces, we r

We develop finite temperature theory for a trapped dipolar Bose gas including thermal exchange interactions. Previous treatments neglected these, difficult to compute, terms. We present a methodology for numerically evaluating the thermal exchange co

A recent paper by T. Papenbrock [Phys. Rev. A 72, 041602(R) (2005)] suggests that a determination of the universal factor ${\ensuremath{\xi}}_{3\mathrm{D}}$ for a harmonically trapped, unpolarized dilute Fermi gas in the unitary regime may be obtaine

The possibility of using ultracold atoms to observe localization of matter waves is now a subject of significant interest. These systems offer unprecedented control over inter-particle interactions, imposed potentials and the level of disorder as com

We investigate a density-functional theory (DFT) approach for an unpolarized trapped dilute Fermi gas in the unitary limit. A reformulation of the recent work of T. Papenbrock [1] in the language of fractional exclusion statistics allows us to obtain

Three distinct types of behaviour have recently been identified in the two-dimensional trapped bosonic gas, namely; a phase coherent Bose-Einstein condensate (BEC), a Berezinskii-Kosterlitz-Thouless-type (BKT) superfluid and normal gas phases in orde

We present numerical results from a full second order quantum field theory of Bose-Einstein condensates applied to the 1997 JILA experiment [D. S. Jin et al., Phys. Rev. Lett. Vol. 78, 764 (1997)]. Good agreement is found for the energies and decay r

The field theory treatments of Base condensed systems developed forty years ago have received renewed attention within the context of inhomogeneous systems since the realisation of Base-Einstein condensation in dilute trapped alkali gases in 1995. Th

In the simulation of low‐pressure plasma discharges using particle‐in‐cell, Monte Carlo collision methods (PIC‐MCC) it is important to obtain good resolution of the electron dynamics. This is obtained by having as low a number of real electro
