Recent developments in dilute quantum gases have raised many deep conceptual questions; they have also generated great interest in possible applications of these systems. This broad field has become highly interdisciplinary, for it now has strong connections with atomic physics, condensed-matter physics, quantum optics, nuclear physics, and quantum information. Thus the conceptual questions are often relevant to several of these areas. One example is the nature of Bose and Fermi gases away from the mean-field regime, which can be achieved either by changing the physical environment of the system (reduced dimension, increased degeneracy, rapid rotation), or by changing the interaction between the atoms(such as tuning the scattering amplitude through a resonance). Another example is the potential use of Bose condensates or degenerate Fermi systems to process quantum information, a topic that has recently attracted much attention. On the practical side, many groups seek to produce(1) a continuous atom laser,(2) an interferometer that detects changes in the gravitational constant and rotational rate,(3) a more accurate atomic clock that makes use of spin squeezing, and(4) more robust qubits for quantum computation, to list only a few examples. All these applications require theoretical studies of the fundamental issues mentioned above. The workshop aims to bring together the most active researchers in this broadly defined field to discuss the numerous important issues. We anticipate that the diverse backgrounds of the participants will make the interactions especially productive.
