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…

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…
