Abstract:

Bose-Einstein condensates as dilute gases and strong correlated Bose systems in traps is reviewed from a theoretical perspective. Mean-field theory provides a framework to understand the main features of the condensation and the role of interactions between atoms. Various properties of Bose-Einstein condensates are discussed, including the density profiles, the energy of ground-state configurations, the collective oscillations and the dynamics of expansion, the condensate fraction and the thermodynamic functions. Despite the dil
