Phase Diagram of Interacting Bosons within Bogoliubov Theory
In my talk I shall describe the Bogoliubov theory as a variational problemin the class of quasi-free states. After deriving the relevant free energyfunctional, I will discuss properties of its minimizers. In particular, Iwill present the resulting phase diagram.
