Caltech/UCLA Joint Analysis Seminar
In this talk, we will review recent progress on the energy of the 3 dimensional dilute Bose gas. It has recently become possible to verify the old prediction by Bogoliubov and Lee-Huang-Yang of the first correction term to the ground state energy of the interacting gas in the thermodynamic limit. If time permits, I will also discuss the relation of these energy results to proofs of "Bose-Einstein condensation" on density dependent length scales.
This is joint work with Jan Philip Solovej.
