A variational approach to the interacting Bose gas
I will discuss an effective, variational model that describes the homogeneous Bose gas in the thermodynamic limit. In particular, I will address the question of how the presence of interactions changes the critical temperature of a Bose-Einstein condensate. I will present results obtained both in 2 and 3 dimensions.
