Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

We theoretically investigate the possibility of slowing and cooling a collisionless atomic gas using a phase-modulated pump field. We consider a single-pump ring cavity with asymmetric cavity losses containing a beam of N polarizable pointlike particles. We show using analytical and numerical analysis that different regimes of the atom-light interaction can be identified and for properly chosen parameters this can lead to effective slowing of the atomic ensemble.
