Coherent functional expansions in quantum field theory
P. D. Drummond
A new formalism is introduced to treat problems in quantum field theory, using coherent functional expansions rather than path integrals. The basic results and identities of this a…
Dynamical Quantum Memories
Q. Y. He, M. D. Reid, E. Giacobino +2
We propose a dynamical approach to quantum memories using an oscillator-cavity model. This overcomes the known difficulties of achieving high quantum input-output fidelity with sto…
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…
Quantum many-body simulations using Gaussian phase-space representations
P. D. Drummond, P. Deuar, J. F. Corney
Phase-space representations are of increasing importance as a viable and successful means to study exponentially complex quantum many-body systems from first principles. This revie…
Gaussian operator bases for correlated fermions
J. F. Corney, P. D. Drummond
We formulate a general multi-mode Gaussian operator basis for fermions, to enable a positive phase-space representation of correlated Fermi states. The Gaussian basis extends exist…
Gaussian phase-space representations for fermions
J. F. Corney, P. D. Drummond
We introduce a positive phase-space representation for fermions, using the most general possible multi-mode Gaussian operator basis. The representation generalizes previous bosonic…
