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…
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…
