Lecture 2: Bogoliubov theory of a dilute Bose gas Abstract
... Superfluidity is an example of spontaneous symmetry breaking of a continuous symmetry. The continuous symmetry is the global U(1) gauge symmetry which is responsible for conservation of total particle number. We shall also carefully distinguish Bose-Einstein condensation from superfluidity. Interact ...
