Rapid production of 87Rb Bose-Einstein condensates in a combined magnetic and optical potential
We describe an apparatus for quickly and simply producing 87Rb Bose-Einstein condensates. It is based on a magnetic quadrupole trap and a red-detuned optical dipole trap. We collect atoms in a magneto-optical trap (MOT) and then capture the atoms in …
Raman processes and effective gauge potentials
A technique is described by which light-induced gauge potentials allow systems of ultracold neutral atoms to behave like charged particles in a magnetic field. Here, atoms move in a uniform laser field with a spatially varying Zeeman shift and experience …
Bose-Einstein Condensate in a Uniform Light-Induced Vector Potential
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
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 …
