Title: Many-body perturbation theory for interacting Bose gases

Abstract: We consider Bose gases with singular interactions among the particles. We investigate the question how and to what extent Rayleigh-Schrödinger perturbation theory can be applied, despite the singularity of the interactions, to derive asymptotic expansions for low-energy properties of the system.

This is based on joint works with Nikolai Leopold, Sören Petrat, Simone Rademacher, and Robert Seiringer.
