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…
Deciding the fate of the false Mott transition in two dimensions by exact quantum Monte Carlo methods
D. Rost, N. Blümer
We present an algorithm for the computation of unbiased Green functions and self-energies for quantum lattice models, free from systematic errors and valid in the thermodynamic lim…
Fate of the false Mott-Hubbard transition in two dimensions
T. Schäfer, F. Geles, D. Rost +6
We have studied the impact of non-local electronic correlations at all length scales on the Mott-Hubbard metal-insulator transition in the unfrustrated two-dimensional Hubbard mode…
Quasi continuous-time impurity solver for the dynamical mean-field theory with linear scaling in the inverse temperature
D. Rost, F. Assaad, N. Blümer
We present an algorithm for solving the self-consistency equations of the dynamical mean-field theory (DMFT) with high precision and efficiency at low temperatures. In each DMFT it…
Momentum-dependent pseudogaps in the half-filled two-dimensional Hubbard model
D. Rost, E. V. Gorelik, F. Assaad +1
We compute unbiased spectral functions of the two-dimensional Hubbard model by extrapolating Green functions, obtained from determinantal quantum Monte Carlo simulations, to the th…
Universal probes for antiferromagnetic correlations and entropy in cold fermions on optical lattices
E. V. Gorelik, D. Rost, T. Paiva +3
We determine antiferromagnetic (AF) signatures in the half-filled Hubbard model at strong coupling on a cubic lattice and in lower dimensions. Upon cooling, the transition from the…
