Spatial Coherence of a Strongly Interacting Bose Gas in the Trimerized Kagome Lattice
Thomas H. Barter, Tsz-Him Leung, Masayuki Okano +3
We produce a trimerized kagome lattice for ultracold atoms using an optical superlattice formed by overlaying triangular lattices generated with two colors of light at a 2:1 wavele…

Mean-field scaling of the superfluid to Mott insulator transition in a 2D optical superlattice
Claire K. Thomas, Thomas H. Barter, Tsz-Him Leung +6
The mean-field treatment of the Bose-Hubbard model predicts properties of lattice-trapped gases to be insensitive to the specific lattice geometry once system energies are scaled b…

Signatures of spatial inversion asymmetry of an optical lattice observed in matter-wave diffraction
C. K. Thomas, T. H. Barter, T. -H. Leung +2
The structure of a two-dimensional honeycomb optical lattice potential with small inversion asymmetry is characterized using coherent diffraction of Rb atoms. We demonstrate…
