1. Few-body physics of ultracold atoms and molecules in confined geometry Vladimir Melezhik Bogoliubov Lab. of Theoretical Physics, JINR, Dubna Outline: Experimental achievements (laser cooling, optical traps, atomic chips) New physics: quantum gases, physics of Bose-Einstein condensations Problems: low-dimensional few-body physics Theoretical models (simple ones) Resent results (extended models) Perspectives, what is going to happen ? 3-5 Feb 2010, Dubna

2. What happens if atoms scatter in excited states? E What happens in collision of two distinguishable particles in a harmonic waveguide if ? What happens if inelastic collisions? Molecule formation?
