简介:The physics of many-body systems strongly depends on their dimensionality. With the realization of quantum wells for example, it has been possible to produce two-dimensional gases of electrons, which exhibit properties that dramatically differ from the standard three-dimensional case, some of them still lacking a full understanding.
During the last decade, a novel environment has been developed for the study of low-dimensional phenomena. It consists of cold atomic gases
that are confined in tailor-made electromagnetic traps. The talk will discuss some experimental aspects of this research, including dynamical
features like the emergence of coherence in the gas when it is rapidly cooled across the superfluid transition.
