Engineering mesoscopic superpositions of superfluid flow
David W. Hallwood, Joachim Brand
Modeling strongly correlated atoms demonstrates the possibility to prepare quantum superpositions that are robust against experimental imperfections and temperature. Such superposi…
Simulating strongly correlated multiparticle systems in a truncated Hilbert space
Thomas Ernst, David W. Hallwood, Jake Gulliksen +2
Representing a strongly interacting multi-particle wave function in a finite product basis leads to errors. Simple rescaling of the contact interaction can preserve the low-lying e…
Robust Mesoscopic Superposition of Strongly Correlated Ultracold Atoms
David W. Hallwood, Thomas Ernst, Joachim Brand
We propose a scheme to create coherent superpositions of annular flow of strongly-interacting bosonic atoms in a 1D ring trap. The non-rotating ground state is coupled to a vortex…
Entanglement enhanced atomic gyroscope
J. J. Cooper, D. W. Hallwood, J. A. Dunningham
The advent of increasingly precise gyroscopes has played a key role in the technological development of navigation systems. Ring-laser and fibre-optic gyroscopes, for example, are…
Measuring atomic NOON-states and using them to make precision measurements
David W. Hallwood, Adam Stokes, Jessica J. Cooper +1
A scheme for creating NOON-states of the quasi-momentum of ultra-cold atoms has recently been proposed [New J. Phys. 8, 180 (2006)]. This was achieved by trapping the atoms in an o…
Scheme for implementing atomic multiport devices
Jessica J. Cooper, David W. Hallwood, Jacob A. Dunningham
Multiport generalizations of beam splitters are the key component in multipath interferometers, which are important in a range of quantum state engineering and precision measuremen…
