Steady states, squeezing, and entanglement in intracavity triplet down conversion
Mathew D. E. Denys, Murray K. Olsen, Luke S. Trainor +2
Triplet down conversion, the process of converting one high-energy photon into three low-energy photons, may soon be experimentally feasible due to advances in optical resonator te…
Mesoscopic dynamical differences from quantum state preparation in a Bose-Hubbard trimer
M. K. Olsen, T. W. Neely, A. S. Bradley
Conventional wisdom is that quantum effects will tend to disappear as the number of quanta in a system increases, and the evolution of a system will become closer to that described…
A quantum correlated twin atom laser from a Bose-Hubbard system
M. K. Olsen, A. S. Bradley
We propose and evaluate a method to construct a quantum correlated twin atom laser using a pumped and damped Bose-Hubbard inline trimer which can operate in a stationary regime. Wi…
Correspondence on "Single-shot simulations of dynamic quantum many-body systems"
M. K. Olsen, J. F. Corney, R. J. Lewis-Swan +1
Comment on a letter to Nature Physics, where Sakmann and Kasevich claim to solve the many-body time dependent Schrödinger equation to simulate single experimental runs of interacti…
Quantum ultra-cold atomtronics
M. K. Olsen, A. S. Bradley
It is known that a semi-classical analysis is not always adequate for atomtronics devices, but that a fully quantum analysis is often necessary to make reliable predictions. While…
Analysis of a continuous-variable quadripartite cluster state from a single optical parametric oscillator
S. L. W. Midgley, A. S. Bradley, O. Pfister +1
We examine the feasibility of generating continuous-variable multipartite entanglement in an intra-cavity quadruply concurrent downconversion scheme that has been proposed for the…
Quadripartite continuous-variable entanglement via quadruply concurrent downconversion
S. L. W. Midgley, A. S. Bradley, O. Pfister +1
We investigate an intra-cavity coupled down-conversion scheme to generate quadripartite entanglement using concurrently resonant nonlinearities. We verify that quadripartite entang…
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…
Bright bichromatic entanglement and quantum dynamics of sum frequency generation
M. K. Olsen, A. S. Bradley
We investigate the quantum properties of the well-known process of sum frequency generation, showing that it is potentially a very useful source of non-classical states of the elec…
Tripartite entanglement and threshold properties of coupled intracavity downconversion and sum-frequency generation
C. Pennarun, A. S. Bradley, M. K. Olsen
The process of cascaded downconversion and sum-frequency generation inside an optical cavity has been predicted to be a potential source of three-mode continuous-variable entanglem…
Teleportation of massive particles without shared entanglement
A. S. Bradley, M. K. Olsen, S. A. Haine +1
We propose a method for quantum state transfer from one atom laser beam to another via an intermediate optical field, using Raman incoupling and outcoupling techniques. Our proposa…
Measuring the quantum statistics of an atom laser beam
A. S. Bradley, M. K. Olsen, S. A. Haine +1
We propose and analyse a scheme for measuring the quadrature statistics of an atom laser beam using extant optical homodyning and Raman atom laser techniques. Reversal of the norma…
Tripartite entanglement from interlinked parametric interactions
M. K. Olsen, A. S. Bradley
We examine the tripartite entanglement properties of an optical system using interlinked interactions, recently studied experimentally in terms of its phase-matching prop…
Continuous variable tripartite entanglement and Einstein-Podolsky-Rosen correlations from triple nonlinearities
M. K. Olsen, A. S. Bradley, M. D. Reid
We compare theoretically the tripartite entanglement available from the use of three concurrent nonlinearities and three independent squeezed states mixed on beamsplitter…
Continuous variable tripartite entanglement from twin nonlinearities
M. K. Olsen A. S. Bradley
In this work we analyse and compare the continuous variable tripartite entanglement available from the use of two concurrent or cascaded nonlinearities. We examine both i…
Phase-space analysis of bosonic spontaneous emission
M. K. Olsen, L. I. Plimak, S. Rebic +1
We present phase-space techniques for the modelling of spontaneous emission in two-level bosonic atoms. The positive-P representation is shown to give a full and complete descripti…
