TL;DR: This work experimentally realizes an optically synthesized magnetic field for ultracold neutral atoms, which is evident from the appearance of vortices in the authors' Bose–Einstein condensate, and uses a spatially dependent optical coupling between internal states of the atoms, yielding a Berry’s phase sufficient to create large synthetic magnetic fields.

TL;DR: This experiment uses an optical lattice of double-well potentials to isolate and manipulate arrays of paired 87Rb atoms, inducing controlled entangling interactions within each pair, and demonstrates the essential component of a neutral atom quantum SWAP gate (which interchanges the state of two qubits), which forms a set of universal gates for quantum computation.

TL;DR: This work uses 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, and their measurements agree quantitatively with a simple single-particle model.

TL;DR: The 2D Bose-Hubbard model is realized by loading a Bose/Einstein condensate into an optical lattice, and the resulting Mott insulator is studied to show a marked dependence on the lattice depth.

TL;DR: A signature of correlation intermediate between that of the uncorrelated, phase coherent, 1D, mean-field regime and the strongly correlated Tonks-Girardeau regime is found.
