     Preparing atom-number states by trap reduction

                   Dr. Adolfo del Campo
                Imperial College, London, UK

While difficult to prepare experimentally, atomic (Fock) states with a
well defined number of particles are highly desirable in atom
interferometry. We shall describe the production of such states from a
large atomic cloud of strongly-interacting bosons/polarized fermions by
suddenly reducing the potential trap. Two different methods are
considered: making the trap shallower and trap squeezing. When used
independently, the efficiency of both procedures is limited, while their
combination provides a robust and efficient strategy to prepare atomic
Fock states.
