An investigation into why macroscopic systems behave classically
David W. Hallwood, Keith Burnett, Jacob Dunningham
We study why it is quite so hard to make a superposition of superfluid flows in a Bose-Einstein condensate. To do this we initially investigate the quantum states of atoms trap…
Entanglement in single particle systems
M. O. Terra Cunha, J. A. Dunningham, V. Vedral
We address some of the most commonly raised questions about entanglement, especially with regard to so-called occupation number entanglement. To answer unambiguously whether entang…
Creation of macroscopic superpositions of flow states with Bose-Einstein condensates
Jacob Dunningham, David Hallwood
We present a straightforward scheme for creating macroscopic superpositions of different superfluid flow states of Bose-Einstein condensates trapped in optical lattices. This schem…
Macroscopic superpositions of superfluid flows
David W. Hallwood, Jacob Dunningham, Keith Burnett
We present a scheme for creating macroscopic superpositions of the direction of superfluid flow around a loop. Using the Bose-Hubbard model we study an array of Bose-Einstein conde…
