Imaging the interface of a qubit and its quantum-many-body environment
S. Rammohan, S. Tiwari, A. Mishra +5
Decoherence affects all quantum systems, natural or artificial, and is the primary obstacle impeding quantum technologies. We show theoretically that for a Rydberg qubit in a Bose…
Macroscopic Quantum Self-Trapping in Dynamical Tunnelling
Sebastian Wüster, Beata J. Dabrowska-Wüster, Matthew J. Davis
It is well-known that increasing the nonlinearity due to repulsive atomic interactions in a double-well Bose-Einstein condensate suppresses quantum tunnelling between the two sites…
Dynamical formation and interaction of bright solitary waves and solitons in the collapse of Bose-Einstein condensates with attractive interactions
B. J. Dabrowska-Wuester, S. Wuester, M. J. Davis
We model the dynamics of formation of multiple, long-lived, bright solitary waves in the collapse of Bose-Einstein condensates with attractive interactions as studied in the experi…
A comparative study of dynamical simulation methods for the dissociation of molecular Bose-Einstein condensates
S. L. W. Midgley, S. Wuester, M. K. Olsen +2
We describe a pairing mean-field theory related to the Hartree-Fock-Bogoliubov approach, and apply it to the dynamics of dissociation of a molecular Bose-Einstein condensate (BEC)…
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…
Supersonic optical tunnels for Bose-Einstein condensates
S. Wuester, B. J. Dabrowska-Wuester
We propose a method for the stabilisation of a stack of parallel vortex rings in a Bose-Einstein condensate. The method makes use of a hollow laser beam containing an optical vorte…
