Creation of macroscopic superposition states from arrays of Bose-Einstein condensates
J. A. Dunningham, K. Burnett, R. Roth +1
We consider how macroscopic quantum superpositions may be created from arrays of Bose-Einstein condensates. We study a system of three condensates in Fock states, all with the same…
Dynamic structure factor of ultracold Bose and Fermi gases in optical lattices
R. Roth, K. Burnett
We investigate the dynamic structure factor of atomic Bose and Fermi gases in one-dimensional optical lattices at zero temperature. The focus is on the generic behaviour of S(k,ome…
Phase Diagram of Bosonic Atoms in Two-Color Superlattices
R. Roth, K. Burnett
We investigate the zero temperature phase diagram of a gas of bosonic atoms in one- and two-color standing-wave lattices in the framework of the Bose-Hubbard model. We first introd…
Ultracold Bosonic Atoms in Disordered Optical Superlattices
R. Roth, K. Burnett
The influence of disorder on ultracold atomic Bose gases in quasiperiodic optical lattices is discussed in the framework of the one-dimensional Bose-Hubbard model. It is shown that…
Exciting Relative Number Squeezed Particles from Condensates Using Stimulated Light Scattering
D. C. Roberts, T. Gasenzer, K. Burnett
We investigate the relative particle number squeezing produced in the excited states of a weakly interacting condensate at zero temperature by stimulated light scattering using a p…
Coherent Dynamics of Vortex Formation in Trapped Bose-Einstein Condensates
B. M. Caradoc-Davies, R. J. Ballagh, K. Burnett
Simulations of a rotationally stirred condensate show that a regime of simple behaviour occurs in which a single vortex cycles in and out of the condensate. We present a simple qua…
