Title: The Lenz term in the ground state energy expansion for a Dilute Bose Gas

Abstract: This talk will be a self-contained introduction to the field of research related to Dilute Bose Gases. After discussing the setting, defining diluteness and the thermodyamic limit, we will give the idea on how to prove the leading order term in the energy expansion for the ground state energy of such systems. More precisely, we will discuss Dyson's argument from '57 for an energy upper bound and the Lieb-Yngvason argument from '98 for a matching lower bound. The talk will finish with a little overview on how energy estimates can be linked to (local) condensation estimates.
