Laser cooling and trapping of atoms
Journal of the Optical Society of America B, 2003A review is presented of some of the principal techniques of laser cooling and trapping that have been developed during the past 20 years. Its approach is primarily experimental, but its quantitative descriptions are consistent in notation with most of the theoretical literature.

Laser cooling and trapping of polariton
Computational Condensed Matter, 2017Abstract An interaction between electrons with photon is an important phenomenon in physics and, particularly, condensed matter and theoretical physics. The result of this interaction yields a quasi-particle called, polariton. In this study we investigated the role of polariton in cooling and trapping processes.

Abstract In previous chapters we have seen how laser spectroscopy gives Doppler free spectra and also how other older techniques of radio-frequency and microwave spectroscopy can resolve small splittings, e.g. hyperfine structure.

Laser cooling and trapping of atoms
Optics News, 1986We recently demonstrated the first optical trapping of atoms. An important prelude to that work was our earlier demonstration of ‘‘optical molasses,’’ a technique for creating a long‐lived collection of ultra‐cold atoms. This paper presents a pedagogical discussion of those experiments and of the background material needed to understand them.

Laser cooling and trapping visualized
American Journal of Physics, 2003Laser cooling and trapping have become widely used in the atomic physics laboratory. A computer program is presented that simulates some of the most important techniques employed, including atomic beam collimation, Zeeman slowing, funneling, and magneto-optical trapping. Its application ranges from experiment design to illustration of course material.

By shining laser light onto an assembly of neutral atoms or ions, it is possible to cool and trap these particles. In this chapter we study a simple cooling mechanism, Doppler cooling, and we derive the corresponding equilibrium temperature. We then show that the cooled atoms can be confined in the potential well created by a focused laser beam.

Laser cooling and trapping of radioactive atoms
SPIE Proceedings, 2003Laser cooling and trapping techniques made possible during the last two decades important achievements in the atomic physics and quantum mechanics fields. These same techniques can be usefully applied to radioactive atoms by opening new fields of investigations. Nuclear processes can be studied with the atomic physics tools. We focused our attention on

European Journal of Physics, 1988
The basic physical effects leading to radiation-induced forces are reviewed. A simple derivation of the mathematical expressions for the classical light forces is given. The influence of quantum fluctuations is demonstrated and the possibilities for trapping neutral particles are discussed.

Optical Society of America Annual Meeting, 1991
The purpose of this tutorial is to introduce the listener to the rapidly developing field of laser cooling and trapping. Doppler cooling is first discussed followed by the new mechanism of cooling based on ground-state energy level shifts in light fields with polarization gradients. Next, the basic concepts of magnetic traps, optical dipole force traps

Applications of laser cooling and trapping
AIP Conference Proceedings, 1991Recent work done at Stanford in the manipulation of atoms and particles is summarized. Techniques to further increase our control of neutral particles such as atomic fountains, funnels, and trampolines have been demonstrated. These techniques are now being combined with a new type of velocity selection in order to study atom/surface interactions and to
