Gradient Echo Quantum Memory for Light using Two-level Atoms
G. Hétet, J. J. Longdell, A. L. Alexander +2
We propose a quantum memory for light that is analogous to the NMR gradient echo. Our proposal is ideally perfectly efficient and provides simplifications to current 3-level quantu…
Non-equilibrium dynamics: Studies of reflection of Bose-Einstein condensates
R. G. Scott, C. W. Gardiner, D. A. W. Hutchinson
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 ex…
Mean-field phase diagram of cold lattice bosons in disordered potentials
P. Buonsante, V. Penna, A. Vezzani +1
We show that a site-dependent mean-field approach captures the quantum phases of the disordered Bose-Hubbard model commonly adopted to describe ultracold bosons in random optical l…
Quantum Scattering of Distinguishable Bosons using an Ultracold Atom Collider
Angela S. Mellish, Niels Kjaergaard, Paul S. Julienne +1
We describe a new implementation of magnetic collider for investigating cold collisions between ultracold atomic clouds in different spin states, and we use this to investigate sca…
Density functional theory of the trapped Fermi gas in the unitary regime
Brandon P. van Zyl, D. A. W. Hutchinson, Melodie Need
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 [Ph…
Transmission and Reflection of Bose-Einstein Condensates Incident on a Gaussian Potential Barrier
A. M. Martin, R. G. Scott, T. M. Fromhold
We investigate how Bose-Einstein condensates, whose initial state is either irrotational or contains a single vortex, scatter off a one-dimensional Gaussian potential barrier. We f…
Disruption of reflecting Bose-Einstein condensates due to inter-atomic interactions and quantum noise
R. G. Scott, D. A. W. Hutchinson, C. W. Gardiner
We perform fully three-dimensional simulations, using the truncated Wigner method, to investigate the reflection of Bose-Einstein condensates from abrupt potential barriers. We sho…
Permutations Containing Many Patterns
M. H. Albert, Micah Coleman, Ryan Flynn +1
It is shown that the maximum number of patterns that can occur in a permutation of length is asymptotically . This significantly improves a previous result of Coleman.
Quantum depletion of collapsing Bose-Einstein condensates
S. Wuester, B. J. Dabrowska-Wuester, A. S. Bradley +4
We perform the first numerical three-dimensional studies of quantum field effects in the Bosenova experiment on collapsing condensates by E. Donley et al. [Nature 415, 39 (2002)] u…
Coupled continuous time random walks in finance
Mark M. Meerschaert, Enrico Scalas
Continuous time random walks (CTRWs) are used in physics to model anomalous diffusion, by incorporating a random waiting time between particle jumps. In finance, the particle jumps…
Thermodynamics of quantum degenerate gases in optical lattices
P. B. Blakie, A. -M. Rey, A. Bezett
The entropy-temperature curves are calculated for non-interacting Bose and Fermi gases in a 3D optical lattice. These curves facilitate understanding of how adiabatic changes in th…
Evidence for social role in a dolphin social network
David Lusseau
Social animals have to take into consideration the behaviour of conspecifics when making decisions to go by their daily lives. These decisions affect their fitness and there is the…
Squeezed state purification with linear optics and feed forward
O. Glöckl, U. L. Andersen, R. Filip +2
A scheme for optimal and deterministic linear optical purification of mixed squeezed Gaussian states is proposed and experimentally demonstrated. The scheme requires only linear op…
Observation of Strong Coupling between One Atom and a Monolithic Microresonator
Takao Aoki, Barak Dayan, E. Wilcut +5
Over the past decade, strong interactions of light and matter at the single-photon level have enabled a wide set of scientific advances in quantum optics and quantum information sc…
Bragg scattering of Cooper pairs in an ultra-cold Fermi gas
K. J. Challis, R. J. Ballagh, C. W. Gardiner
We present a theoretical treatment of Bragg scattering of a degenerate Fermi gas in the weakly interacting BCS regime. Our numerical calculations predict correlated scattering of C…
Permutation Classes of Polynomial Growth
M. H. Albert, M. D. Atkinson, Robert Brignall
A pattern class is a set of permutations closed under the formation of subpermutations. Such classes can be characterised as those permutations not involving a particular set of fo…
Monotonic Sequence Games
M. Albert, R. Aldred, M. Atkinson +4
In a monotonic sequence game, two players alternately choose elements of a sequence from some fixed ordered set. The game ends when the resulting sequence contains either an ascend…
Phase Transitions in Ultra-Cold Two-Dimensional Bose Gases
D. A. W. Hutchinson, P. B. Blakie
We briefly review the theory of Bose-Einstein condensation in the two-dimensional trapped Bose gas and, in particular the relationship to the theory of the homogeneous two-dimensio…
A quantum study of multi-bit phase coding for optical storage
Magnus T. L. Hsu, Vincent Delaubert, Warwick P. Bowen +3
We propose a scheme which encodes information in both the longitudinal and spatial transverse phases of a continuous-wave optical beam. A split detector-based interferometric schem…
Three-body recombination of ultracold Bose gases using the truncated Wigner method
A. A. Norrie, R. J. Ballagh, C. W. Gardiner +1
We apply the truncated Wigner method to the process of three-body recombination in ultracold Bose gases. We find that within the validity regime of the Wigner truncation for two-bo…
Quantum turbulence and correlations in Bose-Einstein condensate collisions
A. A. Norrie, R. J. Ballagh, C. W. Gardiner
We investigate numerically simulated collisions between experimentally realistic Bose-Einstein condensate wavepackets, within a regime where highly populated scattering haloes are…
Thermodynamically activated vortex-dipole formation in a two-dimensional Bose-Einstein condensate
Daniel Schumayer, David A. W. Hutchinson
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-K…
