Title: Generalizations and Applications of Entanglement Swapping
We present a multiparticle generalization of the scheme of entanglement swapping and highlight its applications in quantum information processing. We also present a generalization of entanglement swapping which can be used for local purification of entanglement and show that a new measure of entanglement is conserved in the process. To end, we also illustrate some physical implementations of the above schemes.

Title: Field Theory for Coherent Photoassociation of a Bose-Einstein Condensate
We apply a cubic field theory for the analysis of photoassociation of a Bose-Einstein condensate. We find that, by adiabatically sweeping the frequency of the driving laser, a condensate of atoms may be converted rapidly to a condensate of molecules. Using the corresponding classical field theory, we next study a system of atomic and molecular condensates in equilibrium. All equilibria except the special case with only molecules are prone to an instability whereby the atoms and the molecules collect in dense clumps.
