Strong-coupling approach to the Mott--Hubbard insulator on a Bethe lattice in Dynamical Mean-Field Theory
Daniel Ruhl, Florian Gebhard
We calculate the Hubbard bands for the half-filled Hubbard model on a Bethe lattice with infinite coordination number up to and including third order in the inverse Hubbard interac…

Brueckner-Goldstone perturbation theory for the half-filled Hubbard model in infinite dimensions
Daniel Ruhl, Florian Gebhard
We use Brueckner-Goldstone perturbation theory to calculate the ground-state energy of the half-filled Hubbard model in infinite dimensions up to fourth order in the Hubbard intera…
