Polarization squeezing with cold atoms [PDF]
Physical Review Letters, 2003 We study the interaction of a nearly resonant linearly polarized laser beam with a cloud of cold cesium atoms in a high finesse optical cavity. We show theoretically and experimentally that the cross-Kerr effect due to the saturation of the optical ...

Cooperative Scattering by Cold Atoms [PDF]
Journal of Modern Optics, 2010 We have studied the interplay between disorder and cooperative scattering for single scattering limit in the presence of a driving laser. Analytical results have been derived and we have observed cooperative scattering effects in a variety of experiments,

Cold Atoms Beyond Atomic Physics [PDF]
Brazilian Journal of Physics, 2020 In the last 25 years, much progress has been made producing and controlling Bose-Einstein condensates (BECs) and degenerate Fermi gases. The advances in trapping, cooling and tuning the interparticle interactions in these cold atom systems lead to an unprecedented amount of control that one can exert over them.

Gating Ratchet for Cold Atoms [PDF]
Physical Review Letters, 2008 We demonstrate experimentally a gating ratchet with cold rubidium atoms in a driven near-resonant optical lattice. A single-harmonic periodic modulation of the optical potential depth is applied, together with a single-harmonic rocking force. Directed motion is observed as a result of the breaking of the symmetries of the system.

Cold Heteronuclear Atom-Ion Collisions [PDF]
Physical Review Letters, 2010 We study cold heteronuclear atom ion collisions by immersing a trapped single ion into an ultracold atomic cloud. Using ultracold atoms as reaction targets, our measurement is sensitive to elastic collisions with extremely small energy transfer. The observed energy-dependent elastic atom-ion scattering rate deviates significantly from the prediction of

Observation of spin-space quantum transport induced by an atomic quantum point contact
Nature Communications, 2021 Cold atoms have recently become a versatile platform for the study of quantum transport phenomena. Here the authors realize an alternative experimental scheme for quantum transport with cold atoms, by using spin-dependent impurity scattering in a spinful

Direct loading of Yb atoms into a 3D magneto-optical trap from a dispenser atomic source
AIP Advances, 2023 The realization of cold atoms using a compact and low-power-consumption experimental setup is indispensable for cold atom experiments, including optical clocks and quantum simulations.

Andreev-like reflections with cold atoms [PDF]
, 2008 We propose a setup in which Andreev-like reflections predicted for 1D transport systems could be observed time dependently using cold atoms in a 1D optical lattice.
