Kinetic phenomena of atomic motion in a light field
TLDR
In this paper, the effects of the spatial grating of the cooled atoms, the particle velocity bunching, and the recoil-effect dependence on the nonlinear absorption are considered for slow particles.Abstract:
Kinetic phenomena of resonant-particle motion in a standing-light-wave field are theoretically discussed. The light-pressure force and its fluctuations are found in a wide range of the parameters: the atomic velocity, the intensity, and the detuning of the field. There are two characteristic regions of the detunings in a strong field: the adiabatic region and the region of Landau–Zener resonances. The quantum fluctuations of the inner atomic state that are due to the Landau–Zener transitions result, specifically, in the interference effect in the mean light-pressure force. The effects of the spatial grating of the cooled atoms, the particle velocity bunching, and the recoil-effect dependence on the nonlinear absorption are considered for slow particles. The effect of optical pumping by linearly polarized light taking into account the recoil effect is fundamentally new. Because of this effect, the anisotropic resonance medium becomes gyrotropic.read more

Rectification effect of a radiation force
A. P. Kazantsev,I. V. Krasnov +1 more
TL;DR: In this paper, the rectification effect has been shown to arise in interfering fields, where the spatial RF structure can be either potential or rotational, and the depth of the potential wells generated by the RF can exceed several orders of magnitude the energy of the atom-field interaction.

TL;DR: In this paper, the velocity distribution of atoms cooled in an optical lattice has been studied and the results are supported by full-quantum numerical simulations, showing that a Gaussian function is not the one that best reproduces the data for all parameters.

Cooling and trapping of atoms and molecules by a resonant laser field
TL;DR: In this article, a method for simultaneous cooling and trapping of atoms and molecules in a low-pressure gas under forces caused by recoil during spontaneous or induced transitions of the particles in the resonance field of a three-dimensional standing light wave is proposed.
