{"page":"199 - 215","abstract":[{"lang":"eng","text":"One of the most remarkable recent developments in the study of ultracold Bose gases is the observation of a reversible transition from a Bose Einstein condensate to a state composed of localized atoms as the strength of a periodic, optical trapping potential is varied. In [1] a model of this phenomenon has been analyzed rigorously. The gas is a hard core lattice gas and the optical lattice is modeled by a periodic potential of strength λ. For small λ and temperature Bose- Einstein condensation (BEC) is proved to occur, while at large λ BEC disappears, even in the ground state, which is a Mott-insulator state with a characteristic gap. The inter-particle interaction is essential for this effect. This contribution gives a pedagogical survey of these results."}],"title":"Bose-Einstein condensation as a quantum phase transition in an optical lattice","type":"book_chapter","publist_id":"4559","year":"2006","alternative_title":["LNP"],"volume":690,"author":[{"last_name":"Aizenman","full_name":"Aizenman, Michael","first_name":"Michael"},{"first_name":"Élliott","full_name":"Lieb, Élliott H","last_name":"Lieb"},{"first_name":"Robert","full_name":"Robert Seiringer","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","last_name":"Seiringer","orcid":"0000-0002-6781-0521"},{"first_name":"Jan","full_name":"Solovej, Jan P","last_name":"Solovej"},{"first_name":"Jakob","full_name":"Yngvason, Jakob","last_name":"Yngvason"}],"citation":{"ama":"Aizenman M, Lieb É, Seiringer R, Solovej J, Yngvason J.
