Forward Light Scattering in an Extended Sample of Cold Atoms
… results are interpreted using microscopic light scattering theory as well as techniques from classical optics. The comparison of the two analytical techniques provides a new perspectiveon what is meant by cooperative and collective scattering effects in cold atomic physics.</p>

Hyper-Rayleigh scattering measurements of hyperpolarizabilities for tetrahedral molecules
… and methane have been measured by hyper-Rayleigh scattering in gas and liquid phases. The gas-phase results for the coefficient beta xyz (atomic units) are 11.0 +/- 0.9 (CC14), 5.4 +/- 0.4 (CF4), 7.0 +/- 0.6 (CD4), 7.1 +/- 0.7 (CH4). Ab initio calculations are consistent with the measured values …

Emergence of Collective Light Scattering in Atomic <sup>87</sup>Rb Samples
… We report investigation of near-resonance light scattering from a cold atomic sample of 87Rb. Initially prepared in a magneto-optical trap, the atoms are loaded into a far-off-resonance optical dipole trap (FORT) in which the ensemble has a temperature near 100 mK and initial Gaussian radii of …
