During the last decade, atomic physics has leaped forward due to advances in laser cooling and trapping of neutral atoms. An example of the rapid progress is the recent demonstration of Bose Einstein condensation (BEC) in dilute atomic vapour. This achievement represents a significant advance for many areas of physics. In contrast to other systems displaying the characteristics of BEC, the atoms in a dilute vapour are weakly interacting. It is hoped that the study of this near ideal Bose system will enhance our understanding of related phenomena such as superconductivity and superfluidity.A limitation of existing BEC experiments is that a magnetic trap is used and therefore only one quantum state is confined. The goal of the present proposal is to introduce an additional degree of freedom by transferring the condensate to a second trap (a far-off resonance optical dipole trap) which is not spin selective. In the dipole trap we propose to study long-range interactions and investigate the possibility of observing co-operative type phase transitions such as the formation of an anti-ferromagnetic or a superfluid state.
