LASER-SLOWING AND TRAPPING OF MOLECULES FOR ULTRACOLD CHEMISTRY

Abstract

It would be very interesting if we could apply laser cooling technique directly into molecules.Unfortunately, until recently, laser cooling could not be applied directly to molecules because they generally do not possess suitable closed optical transitions, like in atomic systems. In this proposal, we intend to prepare the next steps of the scientific collaboration between the group at University of São Paulo at São Carlos and the group at Laboratoire Aimé Cotton, CNRS. Our ultimate goal is to study theoretically and experimentally atom-molecule and molecule-molecule collisions within a sample of cold trapped molecules. In this proposal, the main objective of the experimental group at USP-SC will be to achieve laser cooling and trapping of Rb2 molecules from a supersonic molecular beam, based on the simulations elaborated on the molecular structure data available in the theory group at LAC. Moreover, the LAC group will investigate ultracold collisions between Rb atoms and Rb2 molecules, possibly assisted by light, namely photoassociation, which could lead to the formation of trimers Rb3.
