Laser-induced thermal source for cold atoms [PDF]
Scientific Reports, 2022 We demonstrate a simple and compact approach to laser cool and trap atoms based on laser-induced thermal ablation (LITA) of a pure solid granule. A rapid thermalisation of the granule leads to a fast recovery of the ultra-high vacuum condition required ...

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.

Momentum Halo in The Rayleigh Scattering by a Bose–Einstein Condensate
Atoms, 2022 A ring of radius ℏk0 in the momentum distribution of a Bose–Einstein condensate is visible when the atoms scatter a single photon. Here, we describe an approximated theory of this effect, leading to an analytic expression of the isotropic momentum ...

Vacuum pressure measurement of cold 7Li atoms in the magneto-optical and magnetic trap
AIP Advances, 2023 Cold atoms play a very important role in metrology. The ultra-high or extreme-high vacuum pressure can be accurately measured by investigating the collision of cold atoms and residual atoms in the environment. We report a vacuum pressure metrometer using

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.

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 transition produces quadrature squeezing on both the mean field and the orthogonally polarized vacuum ...

Classical and Quantum Collective Recoil Lasing: A Tutorial
Atoms, 2021 Collective atomic recoil lasing (CARL) is a process during which an ensemble of cold atoms, driven by a far-detuned laser beam, spontaneously organize themselves in periodic structures on the scale of the optical wavelength.

Multimode Collective Atomic Recoil Lasing in Free Space
Atoms, 2020 Cold atomic clouds in collective atomic recoil lasing are usually confined by an optical cavity, which forces the light-scattering to befall in the mode fixed by the resonator.
