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 …

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 describe the hybridization-expansion continuous-time quantum Monte Carlo code
package “w2dynamics”, developed in Wien and Würzburg. We discuss the main features of …

We briefly review methods for modeling correlated systems. The concept of correlations is of
fundamental physical importance for systems such as Mott±Hubbard insulators, high …

In this work, we analyze in detail the occurrence of divergences in the irreducible vertex
functions for one of the fundamental models of many-body physics: the Anderson impurity …

We present multiloop flow equations in the functional renormalization group (fRG)
framework for the four-point vertex and self-energy, formulated for a general fermionic many …

We present a multiloop flow equation for the four-point vertex in the functional
renormalization group (FRG) framework. The multiloop flow consists of successive one-loop …

In this work we introduce the dual boson diagrammatic Monte Carlo technique for strongly
interacting electronic systems. This method combines the strength of dynamical mean-filed …

We present a method to treat the two-dimensional (2D) Hubbard model for parameter
regimes which are relevant for the physics of the high-T c superconducting cuprates. Unlike …

Three-particle correlators are relevant for, among others, Raman, Hall, and nonlinear
responses. They are also required for the next order of approximations extending dynamical …
