Momentum structure of the self-energy and its parametrization for the two-dimensional Hubbard model
Petra Pudleiner, Thomas Schäfer, Daniel Rost +3
We compute the self-energy for the half-filled Hubbard model on a square lattice using lattice quantum Monte Carlo simulations and the dynamical vertex approximation. The self-ener…
Mott transitions in the half-filled SU(2M) symmetric Hubbard model
N. Blümer, E. Gorelik
The Hubbard model with large orbital degeneracy has recently gained relevance in the context of ultracold earth alkali like atoms. We compute its static properties in the SU(2M) sy…
Double occupancy as a universal probe for antiferromagnetic correlations and entropy in cold fermions on optical lattices
E. V. Gorelik, T. Paiva, R. Scalettar +2
We verify signatures of antiferromagnetic (AF) correlations in the double occupancy D [Gorelik et al., PRL 105, 065301 (2010)] and study their dimensional dependence using direct q…
Orbital-selective Mott Transitions in a Doped Two-band Hubbard Model
Eberhard Jakobi, Nils Blümer, Peter van Dongen
We extend previous studies on orbital-selective Mott transitions in the paramagnetic state of the half-filled degenerate two-band Hubbard model to the general doped case, using a h…
Numerically exact Green functions from Hirsch-Fye quantum Monte Carlo simulations
N. Blümer
We present a new method for extracting numerically exact imaginary-time Green functions from standard Hirsch-Fye quantum Monte Carlo (HF-QMC) simulations within dynamical mean-fiel…
Efficiency of quantum Monte Carlo impurity solvers for dynamical mean-field theory
N. Blümer
Since the inception of the dynamical mean-field theory, numerous numerical studies have relied on the Hirsch-Fye quantum Monte Carlo (HF-QMC) method for solving the associated impu…
