Dynamical Density-Matrix Renormalization Group for the Mott--Hubbard insulator in high dimensions
Satoshi Nishimoto, Florian Gebhard, Eric Jeckelmann
We study the Hubbard model at half band-filling on a Bethe lattice with infinite coordination number in the paramagnetic insulating phase at zero temperature. We use the dynamical…

Fourth-Order Perturbation Theory for the Half-Filled Hubbard Model in Infinite Dimensions
Florian Gebhard, Eric Jeckelmann, Sandra Mahlert +2
We calculate the zero-temperature self-energy to fourth-order perturbation theory in the Hubbard interaction for the half-filled Hubbard model in infinite dimensions. For the B…
