Comparison of computer-algebra strong-coupling perturbation theory and dynamical mean-field theory for the Mott-Hubbard insulator in high dimensions

Martin Paech, Walter Apel, Eva Kalinowski +1

We present a large-scale combinatorial-diagrammatic computation of high-order contributions to the strong-coupling Kato-Takahashi perturbation series for the Hubbard model in high…

Evaluation of High Order Terms for the Hubbard Model in the Strong-coupling Limit

Eva Kalinowski, Władysław Gluza

The ground-state energy of the Hubbard model on a Bethe lattice with infinite connectivity at half filling is calculated for the insulating phase. Using Kohn's transformation to de…

Ground state of the frustrated Hubbard model within DMFT: energetics of Mott insulator and metal from ePT and QMC

N. Blümer, E. Kalinowski

We present a new method, ePT, for extrapolating few known coefficients of a perturbative expansion. Controlled by comparisons with numerically exact quantum Monte Carlo (QMC) resul…

The Mott insulator - 10th order perturbation theory extended to infinite order using QMC

N. Blümer, E. Kalinowski

We present a new method, based on the combination of analytical and numerical techniques within the framework of the dynamical mean-field theory (DMFT). Building upon numerically e…

Analytical and Numerical Treatment of the Mott--Hubbard Insulator in Infinite Dimensions

Michael P. Eastwood, Florian Gebhard, Eva Kalinowski +2

We calculate the density of states in the half-filled Hubbard model on a Bethe lattice with infinite connectivity. Based on our analytical results to second order in , we prop…

Mott-Hubbard Insulator in Infinite Dimensions

Eva Kalinowski, Florian Gebhard

We calculate the one-particle density of states for the Mott-Hubbard insulating phase of the Hubbard model on a Bethe lattice in the limit of infinite coordination number. We emplo…
