Strong electronic correlations pose one of the biggest challenges to solid state theory.
Recently developed methods that address this problem by starting with the local, eminently …

Quantum impurity models describe an atom or molecule embedded in a host material with
which it can exchange electrons. They are basic to nanoscience as representations of …

Numerical results for ground-state and excited-state properties (energies, double
occupancies, and Matsubara-axis self-energies) of the single-orbital Hubbard model on a …

The Hubbard model represents the fundamental model for interacting quantum systems and
electronic correlations. Using the two-dimensional half-filled Hubbard model at weak …

We present the TRIQS library, a Toolbox for Research on Interacting Quantum Systems. It is
an open-source, computational physics library providing a framework for the quick …

We present TRIQS/CTHYB, a state-of-the art open-source implementation of the continuous-
time hybridisation expansion quantum impurity solver of the TRIQS package. This code is …

The calculation of the electronic properties of materials is an important task of solid-state
theory, albeit particularly difficult if electronic correlations are strong, eg, in transition metals …

A diagrammatic technique is developed to describe nonlocal effects (eg, pseudogap
formation) in the Hubbard-like models. In contrast to cluster approaches, this method utilizes …

Electronic-correlated systems are often well described by dynamical mean field theory
(DMFT). While DMFT studies have mainly focused hitherto on one-particle properties …

We study the expansion of single-particle and two-particle imaginary-time Matsubara
Green's functions of quantum impurity models in the basis of Legendre orthogonal …
