Coherent States for a Bosonic Atom-Molecule Conversion Systems — •Wasim Rehman1 and Eva-Maria Graefe21Imperial College, London, UK — 2Imperial College, London, UK

Coherent states are of great importance in quantum mechanics, in particular for the investigation of quantum-classical correspondence. Here I will consider a simple two-state quantum model of atom-molecule conversion in cold atom systems, where bosonic atoms can combine into diatomic molecules and vice versa. The many-particle system can be expressed in terms of the generators of a deformed SU(2) algebra. In this context the question of what the relevant coherent states are had so far not been fully addressed. Here I will present candidates for the coherent states for this system and analyse their properties and resulting phase-space structures.
