Orbital-selective Mott transitions in the anisotropic two-band Hubbard model at finite temperatures
C. Knecht, N. Blümer, P. G. J. van Dongen
The anisotropic degenerate two-orbital Hubbard model is studied within dynamical mean-field theory at low temperatures. High-precision calculations on the basis of a refined quantu…
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…
The LDA+DMFT Approach to Materials with Strong Electronic Correlations
K. Held, I. A. Nekrasov, G. Keller +7
LDA+DMFT is a novel computational technique for ab initio investigations of real materials with strongly correlated electrons, such as transition metals and their oxides. It combin…
