Bose-Einstein Condensate in a Uniform Light-Induced Vector Potential

By Ian Spielman Posted on 2009/03/30 Posted in Papers Published, RbK

We use a two-photon dressing field to create an effective vector gauge potential for Bose-Einstein-condensed 87Rb atoms in the F=1 hyperfine ground state. These Raman-dressed states are spin and momentum superpositions, and we adiabatically load the atoms into the lowest …

Condensate Fraction in a 2D Bose Gas Measured across the Mott-Insulator Transition

By Ian Spielman Posted on 2008/03/26 Posted in Papers Published

We realize a single-band 2D Bose-Hubbard system with Rb atoms in an optical lattice and measure the condensate fraction as a function of lattice depth, crossing from the superfluid to the Mott-insulating phase. We quantitatively identify the location of the …
