Entanglement, number fluctuations and optimized interferometric phase measurement
Q. Y. He, T. G. Vaughan, P. D. Drummond +1
We derive a phase-entanglement criterion for two bosonic modes which is immune to number fluc- tuations, using the generalized Moore-Penrose inverse to normalize the phase-quadratu…
Quantum dynamics in phase space: From coherent states to the Gaussian representation
P. D. Drummond, P. Deuar, T. G. Vaughan +1
We give an outlook on the future of coherence theory and many-body quantum dynamics as experiments develop in the arena of ultra-cold atoms. Novel results on quantum heating of cen…
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…
Quantum limits to center-of-mass measurements
Timothy Vaughan, Peter Drummond, Gerd Leuchs
We discuss the issue of measuring the mean position (center-of-mass) of a group of bosonic or fermionic quantum particles, including particle number fluctuations. We introduce a st…
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…
