Abstract

E.A. Schoene et al., in arXiv:1012.3207 [Phys. Rev.A, 82, 023419 (2010)] give incorrect interpretation of their experimental results. Really we observe a temporary capture and additional cooling of atoms in the presence of the orthogonal laser beam. Any strong potential barriers are absent here. It may be easily experimentally tested.

We demonstrate the use of a moving optical one-way barrier for cooling a collection of atoms, and how sensitive this method is to varying experimental parameters.

Laser cooling of atoms: a review

Vladilen S Letokhov, Maxim Olshanii, Yu. B. Ovchinnikov

The present brief review is aimed at expounding the current status of the problem of cooling of neutral atoms so as to make it easy to grasp by physicists not actively engaged in this area. The basic concepts of laser cooling and the most illuminating experiments are discussed.

Cooling atoms with a moving one-way barrier

Elizabeth A. Schoene, Jeremy J. Thorn, D. Steck

We implement and demonstrate the effectiveness of a cooling scheme using a moving, all-optical, one-way barrier to cool a sample of $^{87}\mathrm{Rb}$ atoms, achieving nearly a factor of 2 reduction in temperature. The one-way barrier, composed of two focused, Gaussian laser beams, allows atoms incident on one side to transmit, while reflecting atoms incident on the other. The one-way barrier is adiabatically swept through a sample of atoms contained in a far-off-resonant, single-beam, optical dipole trap that forms a nearly harmonic trapping potential. As the barrier moves longitudinally through the potential, atoms become trapped to one side of the barrier with reduced kinetic energy. The adiabatic translation of the barrier leaves the atoms at the bottom of the trapping potential, only minimally increasing their kinetic energy.We implement and demonstrate the effectiveness of a cooling scheme using a moving, all-optical, one-way barrier to cool a sample of $^{87}\mathrm{Rb}$ atoms, achieving nearly a factor of 2 reduction in temperature.

Ultracold collisions and optical shielding in metastable xenon

Kalle‐Antti Suominen, Keith R. Burnett, Paul S. Julienne +5 more

Collisions between laser-cooled metastable xenon atoms in the presence of laser fields provide a good experimental test for ultracold collision theories as the observed ionization can be directly linked to the atomic binary collisions. Hyperfine structure is not present for the even isotopes ${\mathrm{Xe}}^{132}$ and ${\mathrm{Xe}}^{136}$ , which simplifies the theoretical work. We present our results and show how these and the results presented in Walhout et al. [Phys. Rev. Lett. 74, 605 (1995)] can be interpreted with suitably adapted two-state models. Our approach suggests one possibility why the strong shielding of collisions predicted by the simple two-state model of Suominen et al. [Phys. Rev. A 51, 1446 (1995)] has not been achieved in the xenon experiment. \textcopyright{} 1996 The American Physical Society.Collisions between laser-cooled metastable xenon atoms in the presence of laser fields provide a good experimental test for ultracold collision theories as the observed ionization can be directly linked to the atomic binary collisions.
