On Asymptotic Expansions in Spin Boson Models
Gerhard Bräunlich, David Hasler, Markus Lange
We consider expansions of eigenvalues and eigenvectors of models of quantum field theory. For a class of models known as generalized spin boson model we prove the existence of asym…

Bogolubov-Hartree-Fock theory for strongly interacting fermions in the low density limit
Gerhard Bräunlich, Christian Hainzl, Robert Seiringer
We consider the Bogolubov-Hartree-Fock functional for a fermionic many-body system with two-body interactions. For suitable interaction potentials that have a strong enough attract…
