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…

Blind deconvolution of density-matrix renormalization-group spectra
Martin Paech, Eric Jeckelmann
We present a numerical method for calculating piecewise smooth spectral functions of correlated quantum systems in the thermodynamic limit from the spectra of finite systems comput…
