Correlation Effects in Ultracold Two-Dimensional Bose Gases
Lih-King Lim, C. Morais Smith, H. T. C. Stoof
We study various properties of an ultracold two-dimensional (2D) Bose gas that are beyond a mean-field description. We first derive the effective interaction for such a system as r…

Staggered-Vortex Superfluid of Ultracold Bosons in an Optical Lattice
Lih-King Lim, C. Morais Smith, Andreas Hemmerich
We show that the dynamics of cold bosonic atoms in a two-dimensional square optical lattice produced by a bichromatic light-shift potential is described by a Bose-Hubbard model wit…
