Forward Light Scattering in an Extended Sample of Cold Atoms
… results on the forward emitted light from a cold atomic sample of 87Rb. Specifically,we study single-photon superradiance which is characterized by a rapid decay faster than the single atom lifetime with the light preferentially emitted in the forward direction. Additionally, we report …

Transport properties of a Bose-Einstein condensate with tunable interactions in the presence of a disordered or single defect potential
… of the foundational models of condensed matter physics. The observation of a critical velocity for the breakdown of superfluidity in a BEC and the superfluid to Mott insulator transition observed in a BEC trapped by an optical lattice are but two examples of the, by now, dozens of exciting …

CORRELATED PHOTON PAIRS AND MULTIPHOTON STATES FROM A COLD ATOMIC ENSEMBLE
… of 780 nm and 795 nm in an optically dense cold <sup>87</sup>Rb ensemble. The source is based on a spontaneous four-wave mixing process implemented in a double-Λ energy-level configuration. By systematically varying the pump intensities, detunings, and optical depth, we optimized the …
