Summary on Grant Application Form
The last decade has witnessed an explosion of activity in the field of quantum degenerate gases. At present it is possible to identify several hot topics which are likely to form the basis for research in this field in the immediate future. These include:1. The use of magnetic field induced collisional resonances (Feshbach resonances) both to control the interactions within a quantum degenerate gas and as a means to produce ultracold molecules.2. The realization of mixtures of two different quantum degenerate atomic gases.3. The study of quantum degenerate gases in regular lattice potentials formed by standing-wave light fields (optical lattices) and their applications to quantum computation.The main objective of this proposal is to produce a two-component quantum degenerate mixture composed of Bose-Einstein condensates of 87Rb and 133CS in a highly adjustable optical trapping potential. This particular combination of atomic species permits the study of all of the hot topics listed above in a single, flexible experimental system.The specific long term goal of this research is to produce ultracold dipolar molecules from the two-component quantum degenerate mixture. The proposed method requires the production of an optical lattice with exactly one caesium and one rubidium atom per lattice site. This will be achieved by exploiting a quantum phase transition from a superfluid to an insulator state (the Mott insulator transition). Ultracold heteronuclear molecules will be created either by photoassociation or by utilising a Feshbach resonance.
