Detection of continuous variable entanglement without coherent local oscillators
A. J. Ferris, M. K. Olsen, E. G. Cavalcanti +1
We propose three criteria for identifying continuous variable entanglement between two many-particle systems with no restrictions on the quantum state of the local oscillators used…
Dynamical instabilities of Bose-Einstein condensates at the band-edge in one-dimensional optical lattices
Andrew J. Ferris, Matthew J. Davis, Reece W. Geursen +2
We report on experiments that demonstrate dynamical instability in a Bose-Einstein condensate at the band-edge of a one-dimensional optical lattice. The instability manifests as ra…
Control of an atom laser using feedback
S. A. Haine, A. J. Ferris, J. D. Close +1
A generalised method of using feedback to control Bose-Einstein condensates is introduced. The condensates are modelled by the Gross-Pitaevskii equation, so only semiclassical fluc…
