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 ?
