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…
Cold atom gravimetry with a Bose-Einstein Condensate
J. E. Debs, P. A. Altin, T. H. Barter +6
We present a cold atom gravimeter operating with a sample of Bose-condensed Rubidium-87 atoms. Using a Mach-Zehnder configuration with the two arms separated by a two-photon Bragg…
Optically trapped atom interferometry using the clock transition of large Rb-87 Bose-Einstein condensates
P. A. Altin, G. McDonald, D. Döring +7
We present a Ramsey-type atom interferometer operating with an optically trapped sample of 10^6 Bose-condensed Rb-87 atoms. The optical trap allows us to couple the |F =1, mF =0>\r…
