Coherence and Correlations in Atom Lasers
P. D. Drummond, T. Vaughan, J. F. Corney +2
We review and characterize the quantum coherence measures that are most useful for quantum gases, including Bose-Einstein condensates (BEC) and ultra-cold fermions, and outline how…
Excitation spectrum of bosons in a finite one-dimensional circular waveguide via the Bethe ansatz
Andrew G. Sykes, Peter D. Drummond, Matthew J. Davis
The exactly solvable Lieb-Liniger model of interacting bosons in one-dimension has attracted renewed interest as current experiments with ultra-cold atoms begin to probe this regim…
Quantum phase-space simulations of fermions and bosons
P. D. Drummond, J. F. Corney
We introduce a unified Gaussian quantum operator representation for fermions and bosons. The representation extends existing phase-space methods to Fermi systems as well as the imp…
Ultra-cold fermions in optical lattices
P. D. Drummond, J. F. Corney, X. -J. Liu +1
We summarize recent theoretical results for the signatures of strongly correlated ultra-cold fermions in optical lattices. In particular, we focus on: collective mode calculations,…
First-principles quantum dynamics in interacting Bose gases II: stochastic gauges
P. Deuar, P. D. Drummond
First principles simulations of the quantum dynamics of interacting Bose gases using the stochastic gauge representation are analyzed. In a companion paper, we showed how the posit…
Three-dimensional solitons in coupled atomic-molecular Bose-Einstein condensates
T. G. Vaughan, K. V. Kheruntsyan, P. D. Drummond
We present a theoretical analysis of three-dimensional (3D) matter-wave solitons and their stability properties in coupled atomic and molecular Bose-Einstein condensates (BEC). The…
